The urgency of proactive actions for improving the resilience and sustainability of the built environment is one of today’s critical tasks in Civil Engineering. In this perspective, robust and reliable optimization procedures offer immense promise and transformative potential for mitigating seismic risk.

Traditional seismic design methodologies often prioritize safety, leading to solutions that are either cost-prohibitive or require time-consuming design iterations. On the other hand, advanced optimization algorithms and frameworks can be strategically employed throughout the structure's entire lifecycle, allowing practitioners to explore a broader range of design options that are not only structurally sound but also cost-effective, efficient, and environmentally sustainable.

This mini-symposium proposes a paradigm shift in this domain.

From structural monitoring and assessment to the design of retrofitting strategies, optimization tools allows to glean deeper insights into structural health, predict potential vulnerabilities with enhanced accuracy, and design more targeted and cost-effective retrofitting interventions when necessary.

The aim of this mini-symposium is to convene academics and practitioners in the field of civil engineering, computer science, and disaster risk management in order to foster the exchange of latest advancements and experiences on the optimum design and control of structures for seismic risk reduction.

Topics of interest include (but are not limited to) the following themes:

  • advanced algorithms and computational technologies specifically tailored for design and control of structures;
  • application of Artificial Intelligence tools for seismic risk reduction;
  • establishment of best practices for successfully integrating optimization algorithms with traditional design methodologies on real-world structures.

Offshore wind energy is currently one of the most rapidly expanding sectors within the global energy industry. In parallel with the growth in demand for renewable energy, there has been a proportional increase in the size and capacity of wind turbines (WTs). Larger turbines can capture more wind energy, making them more efficient and cost-effective. Consequently, the current design trends for WTs are characterized by the development of increasingly larger rotors and the construction of more slender and taller towers. These structures are subjected to a multitude of environmental loads that can significantly impact their design and operation. The most critical of these loads include the combined effects of wind and sea waves, as well as seismic forces in areas prone to earthquakes. These loads result in substantial structural vibrations and fatigue within the tower and foundation, which may ultimately lead to structural failures. To ensure the longevity and reliability of wind turbines, it is imperative to both mitigate the induced structural vibrations and enhance their design.

This minisymposium focuses on addressing the critical challenge of mitigating ambient vibrations, such as those caused by earthquakes, wind, and wave loading, particularly in wind turbine structures. Experts and researchers from multidisciplinary backgrounds are encouraged to propose innovative strategies and technologies aimed at strengthening wind turbine towers, ensuring their structural integrity and operational efficiency. Among the topics of discussion are recent vibration control strategies, including passive, semi-active, and active control techniques. Some of these strategies involve the utilization of Tuned Mass Dampers (TMDs), TMDs with inerters (TMDIs), and devices incorporating negative stiffness (NS) elements.

This minisymposium encourages the submission of research papers presenting new findings in the fields of computational modeling, experimental testing, and optimization of novel vibration control systems implemented in wind turbine structures for vibration mitigation.

Artificial Intelligence can process vast amounts of data using fast, iterative, and intelligent algorithms, enabling software to automatically 'learn' from diverse input data. One key application of AI is Machine Learning, which automates the creation of analytical models. Machine Learning allows computers to learn without explicit programming. In recent years, Machine Learning has advanced rapidly, promising to significantly transform and enhance the role of data science across various fields. A comprehensive review reveals that Machine Learning has been utilized in four key areas of earthquake engineering: seismic hazard analysis, system identification and damage detection, seismic fragility assessment, and structural control for earthquake mitigation.

Machine Learning is poised to significantly advance research and practice in earthquake engineering. Currently, there are two main approaches in this field: physics-based methods, which are transparent, interpretable, and somewhat predictable, and data-driven Machine Learning models, which are often not unique and can be difficult to interpret. Consequently, there is a growing trend toward finding a balance between these approaches. Since the lack of physical interpretation in Machine Learning models can limit their applicability to similar problems, integrating physical knowledge into Machine Learning-based earthquake engineering studies is essential. Despite the increasing number of studies, the application of Machine Learning in earthquake engineering is still in its early stages compared to other disciplines. However, with the support of next-generation data sharing and sensor technologies, Machine Learning holds great potential to revolutionize earthquake engineering.

As previously mentioned, Machine Learning has been applied in four key areas of earthquake engineering: seismic hazard analysis, system identification and damage detection, seismic fragility assessment, and structural control for earthquake mitigation. The literature identifies seven classes of Machine Learning methods: artificial neural networks, support vector machines, response surface models, logistic regression, decision trees, random forests, and hybrid methods that combine multiple soft computing algorithms, such as fuzzy logic. This Minisymposium invites presentations on all these topic areas and Machine Learning methods in earthquake engineering.

The engineering community has widely acknowledged and accepted the importance of accounting for the effects of uncertainty on the performance of engineering systems subject to time-varying loading. Among others, this is also dictated by the need to efficiently account for the uncertainty pertaining to modelling natural excitations such as seismic and wind loads. The latter often exhibit time-varying characteristics, which are better captured by resorting to a stochastic processes-based modelling. In addition, the explicit quantification of the uncertainty in structural systems, in particular, is an extremely challenging task since highly refined numerical models are already used to characterize the system performance. It is thus clear that accounting for uncertainties adds additional levels of complexity over the (already challenging) dynamic deterministic analysis. Hence, there is an evident and ever-increasing need to develop efficient numerical methods that allow quantifying uncertainty for analysis of dynamical systems.

This mini-symposium aims at presenting the latest developments and approaches for uncertainty quantification in the field of computational stochastic dynamics. The scope of the mini-symposium is broad, as it includes different types of linear and nonlinear structural problems; the development of novel advanced simulation approaches, path integration- and probability-density-based methods, as well as metamodeling-based frameworks; model identification in stochastic systems; and practical applications of methods for uncertainty quantification in stochastic dynamics comprising, e.g., robust design, reliability-based design, multi-objective optimization, life-cycle optimal design, sensitivity analysis, model updating, etc. Both theoretical developments and practical applications involving systems of engineering interest are particularly welcomed.

Key words: stochastic dynamics, uncertainty propagation, dynamical response.

Most part of masterpieces and art collections are stored in historical buildings used as Museums. Such buildings are usually very sensitive to vibrations since they were built without any anti-seismic regulations. Their dynamic properties, therefore, can largely affect the safety of the exhibited artifacts, which can easily be very vulnerable, due to their age, materials, and features. At the occurring of seismic excitations, art collections can experience relevant damages, and the most vulnerable items can be destroyed. However, even for ordinary occurrences, the vibrations can be a threat, affecting the safety and the conservation properties of some items.

This session is focused on the dynamic monitoring and analysis of both historical buildings used for exhibition and pieces of art. A special attention is devoted to the combined effects of the dynamic response of container and content due to external excitations. Both exceptional excitations, such as earthquakes and explosions, and ordinary ones, such as micro-seismic activities, wind, visitors walking, vehicular traffic and construction works, should be taken into account. The session collects all the contributions, both theorical and experimental, devoted to this field, ranging from general issues to specific case-studies.

The main topics faced by the session include:

- Dynamic monitoring and/or analysis of masterpieces, artifacts and art collections
- Dynamic monitoring and/or analysis of historical-monumental buildings
- Dynamic monitoring and/or analysis of Museums
- Seismic assessment of masterpieces, artifacts and art collections
- Seismic assessment of historical-monumental buildings
- Design of innovative devices for increasing the seismic safety of art collections and monumental building

Knowledge, preparedness, prevention, and mitigation of seismic risks are central to the work of numerous scientific and engineering communities in Europe and beyond, driven by the significant loss of life, property, and infrastructure experienced in recent decades. In the face of ongoing disruptive climate changes, both natural and human-induced hazards increasingly affect urban areas and communities. It is now recognized that safeguarding human settlements and natural heritage from natural hazards requires a holistic and comprehensive approach, considering the potential simultaneous occurrence and interaction of various hazards. This principle forms the basis of the RETURN project—Multi-risk Science for Resilient Communities under a Changing Climate, funded by the NextGenerationEU Program of European Union.

This Minisymposium seeks to promote discussion on the seismic response of structures that have previously been impacted by other natural or human-induced hazards (such as volcanic activity, landslides, ground instability, fires, and floods), as well as on the response of structures to such hazards following an earthquake.

While the primary focus is on analytical and numerical investigations, contributions on related topics, including impact chains, risk management, population preparedness, multi-criteria analysis of mitigation actions, and civil protection activities, are also welcome.

Many Reinforced Concrete (RC) buildings in seismic-prone regions were constructed before the implementation of current seismic regulations and therefore do not adhere to modern anti-seismic design philosophies. As a result, the structural safety of these buildings is often inadequate when subjected to seismic forces, posing significant risks to renovation investments in the event of an earthquake. Replacing existing buildings with new, compliant structures is not economically feasible and would entail substantial environmental and social repercussions.

Also, masonry infill walls play a critical role in modifying the seismic response of RC buildings. Their irregular distribution can lead to various failure mechanisms. Most existing structures were not designed to account for the effects of masonry infill walls, which significantly increases their vulnerability. Nevertheless, the high out-of-plane vulnerability of these infill walls has been responsible for numerous collapses, casualties, and economic losses during seismic events. Extensive numerical and experimental research is being conducted to understand how different parameters of these infill walls affect their seismic performance.

Moreover, considering the impact of buildings on global energy consumption, future renovation efforts must address both seismic and energy performance improvements. This special session will feature presentations followed by a round-table discussion, focusing on several key topics including but not limited to:

  • Seismic performance assessment methodologies of RC structures
  • Experimental testing and numerical simulation of RC individual elements and/or RC frames
  • Experimental and numerical studies on the seismic behaviour of masonry infill walls and/or infilled RC frames
  • Independent or integrated retrofit techniques for reinforced concrete frame structures
  • Cost-effectiveness evaluation of retrofitting strategies at regional or national levels

By addressing these topics, the session aims to advance the knowledge and application of integrated retrofitting approaches, ensuring the structural integrity and sustainability of buildings in seismic zones.

Predicting the dynamic behavior of periodic structures via advanced numerical methods is a challenging problem which has gained large popularity over the past decades. This includes the analysis of resonant metamaterials with band gap phenomena where the need of efficient numerical methods is becoming crucial, e.g., for fast reanalysis and design of engineering systems with optimized vibration levels. In this framework, this minisymposium aims at discussing advanced modeling strategies for periodic structures and metamaterials with complex cells like those encountered in practical engineering applications. These cells can represent 2D or 3D substructures or multi-physic subsystems that usually involve many internal and boundary degrees of freedom. In this context, the development of reduced order models is becoming crucial to undertake numerical simulations in affordable times. The topics of the minisymposium include:

  • Wave-based approaches: wave finite element (WFE) method, plane wave expansion (PWE) method, Bloch mode expansion, energy-based methods…
  • Nearly periodic structures, substructures with parametric changes, uncertainties.
  • Nonlinear periodic structures.

Seismic performance of non-structural components (NSCs) in buildings is currently one of the hottest topics in structural engineering, considering that their seismic response turned out to have a high impact on the life safety and economic losses. Some NSCs may directly affect the serviceability of buildings (partition walls, piping systems), whilst other NSC typologies have direct and indirect economic and social consequences (artistic assets) as well as safety issues (equipment in nuclear power plants). In all cases, according to the NSC sensitivity to dynamic actions (to floor accelerations, displacements, or both), the correct definition of the seismic demands is needed both for design and assessment purposes, and it is commonly provided in terms of floor response spectra (FRS). The most important factors that influence FRS have been recognized by the scientific community, and there is a constant tendency to improve the state-of-knowledge on them. In this field, the main goal of the research efforts is to provide engineers with more accurate but simple approaches for the NSC seismic design and assessment. At the same time, significant efforts are still required to provide the practitioners with seismic performance parameters, obtained from experimental testing or advanced numerical analy`ses, useful in the performance-based seismic design framework.

This Minisymposium aims to promote and share the latest achievements about the definition of the seismic demands to which NSCs are prone and the assessment of their performance both through advanced numerical analyses and experimental testing.

The expected contributions may include (but are not limited to):

- Numerical and experimental studies on NSCs.
- FRS in new and existing structures.
- Methodologies for the performance-based seismic design of NSCs.
- Assessment of NSCs in existing structures.
- NSCs response in elastic and inelastic field.
- Monitoring techniques for NSCs.
- Retrofit solutions for seismic risk mitigation.
- Approaches and provisions in design codes.

Existing structures designed/constructed without modern seismic design provisions represent one of the largest seismic safety concerns worldwide. Such structures are vulnerable to significant structural and non-structural damage and even collapse when subjected to medium-to-strong ground shaking. This resulted in number of fatalities and significant economic losses, which promoted the development of seismic assessment and retrofit procedures for existing structures.

Recent devastating earthquakes pointed out the need for new, practical, and cost-effective seismic strengthening solutions that can be applicable at regional and with minimum level of disruption to the occupants. Over the past three decades, several techniques emerged. Fiber-reinforced polymer (FRP), Fiber Reinforced Cementitious Matrix (FRCM), High Performance Fiber Reinforced Cementitious Composites (HPFRCC) composites, base isolation, dissipative devices, low-damage systems gained popularity as attractive solutions for repair and retrofit of civil infrastructures. They are successfully used for strengthening/rehabilitation of existing buildings and bridges. However further research effort is needed to improve their effectiveness, develop new applications, numerical modelling, design procedures, and techniques for installation. Furthermore, computational efficient simulations are needed to assess the benefits of seismic risk mitigation strategies at regional scale.

In this context, the mini symposium intends to attract academic staff, researchers, post-graduate students and professional engineers dealing with seismic repair and retrofit of structures, such as buildings and bridges, with innovative materials or with innovative seismic devices. The refinements in the analysis, assessment of residual capacity, design procedures and simulation to assess the benefits of interventions at regional scale are of particular interest.

To guarantee the safety of roadway and railway networks, transport authorities’ operators daily perform structural safety assessments of existing bridges and viaducts, dealing with several challenges. First, in developed countries such as Italy and Greece, there is a significant number of existing bridges, which were designed in the past according to obsolete design codes, in need of appropriate structural assessment considering the current service needs. The multitude of bridges to be evaluated contrasts with the limited availability of financial resources, time, and manpower of transport authorities. Furthermore, bridge structural assessment should consider the detrimental actions of natural and human-induced hazard sources which, as shown by recent disasters, can affect the safety of bridges and were not appropriately considered by design prescriptions in the past. In addition, many existing bridges located in aggressive environments suffer degradation phenomena severely impacting the structural capacity of bridge components.

To prevent relevant economic losses and to safeguard life safety, the definition of reliable risk-informed prioritisation and assessment to address mitigation strategies on critical bridges is essential. To this scope, different levels of investigation are required, from the large-scale screening of bridge portfolios to the detailed bridge-specific assessment. To this scope, the scientific community is called upon to develop new methodologies for efficient structural assessment approaches to be implemented in bridge management systems and possibly supported by advances in new technologies (e.g., remote-sensing approaches, sensor-based monitoring) or novel computational strategies (e.g., machine-learning techniques).

This Minisymposium aims to promote and share the latest research advances and achievements in risk-informed prioritisation, assessment, and mitigation to ensure the safety of existing bridges. The expected contributions may include (but are not limited to):

  • Innovative methodologies for onsite bridge inspection;
  • Photogrammetry, 3D lidar scanning, and point cloud processing for bridge digital twinning;
  • Automatic defect detection using artificial intelligence algorithms.
  • Monitoring techniques for bridges;
  • Adoption of monitoring and onsite inspection data for refined finite element modelling calibration;
  • Risk-informed prioritisation considering multiple hazard sources;
  • Advances in bridge structural assessment;
  • Numerical and experimental studies on structural behaviour of bridge components;
  • Maintenance and retrofit solutions for risk mitigation;
  • Cost/benefit analyses aimed at the identification of the optimal retrofitting solution.

As urban populations grow, cities face the challenge of accommodating diverse structures while increasing the spatial density of buildings.

In this regard, the seismic resilience of structures has become an important parameter in earthquake engineering. In particular, it is well known that the effects of the soil structure interaction (SSI) may reduce the resilience of the systems and urban communities. In addition, the traditional seismic analysis considers buildings as stand-alone structures, with no neighbouring structures. Yet dense urban configuration introduces a significant, often unquantified interaction between adjacent buildings through the underlying soil, known as Structure-Soil-Structure Interaction (SSSI). Therefore, it is non-conservative to neglect SSI in the assessments of the seismic resilience of structures, particularly in those cases of interbuilding dynamic interactions. This potential risk to existing property owners represents an unquantified liability within the current seismic code framework. Thus, neglecting the increased seismic risk for some particular cases due to coupling adjacent buildings through the underlying soil is no longer reasonable.

This minisymposium focuses on novel approaches that can assess seismic resilience by addressing the leading developments of SSI, SSSI and Site-City Interaction effects (SCI), using different techniques such as:

(i) Numerical methods (Finite Element Method, Boundary Element Method or hybrid Finite/Boundary Element Method),

(ii) Analytical methods or reduced-order methods.

(iii) Experimental methods (centrifuge and shaking table tests).

The mini symposium "Interpretable Machine Learning for Natural Hazards, Exposure, and Risk Modelling" aims to address the critical need for transparency and explainability in the application of advanced machine learning and deep learning techniques to natural hazard, exposure, and risk modelling. Despite the versatility of machine learning (ML) and deep learning (DL) models for engineering applications, the practicing communities face challenges in implementing these due to their Blackbox nature. Hence it is critical to provide sufficient analytics for model interpretability and its response in terms of predictions based on variability in the inputs. Transparent/translucent models not only enable better decision-making, foster trust among stakeholders, and ensure better safety measures but are also easier to debugging and regulating.

With the emergence of explainable artificial intelligence (XAI) and physics/domain-informed ML, various concepts and algorithms have been developed that improve the understanding of AI systems output and operation, such as global and local feature importance-based metrics, game-theory-based algorithms, physics-informed optimization, physics-informed neural networks, counterfactual and contrastive example-based techniques, and causal inferences. The symposium focuses to bridge the gap between advanced ML/DL methods and their practical, interpretable applications in the field of natural hazard, exposure, and risk modelling.

Key topics include (but are not limited to) the application of XAI and physics/domain-informed ML/DL for:

  • Earthquake Early Warning Systems.
  • Ground Motion Modelling and Ground Motion Simulations.
  • Probabilistic Hazard Analysis (for Earthquakes, Floods, Winds, etc).
  • Structural Health Monitoring.
  • Surrogate Modelling of Structures.
  • Multi-Hazard Modelling and Analysis.
  • Exposure Modelling.
  • Performance-Based Engineering.
  • Risk-Based Design and Assessment.
  • Community Infrastructural Modelling.

This mini symposium invites contributions that highlight advancements in the interpretability of ML/DL models through XAI and/or physics-informed modelling, case studies demonstrating practical applications, and innovative methodologies that enhance the reliability and transparency of predictive modelling in the context of mitigation of natural hazards and structural modelling.

Precast concrete buildings were observed to be affected by significant damage following the recent strong earthquakes around the world.
The conducted surveys highlighted how the most widespread damages resulted in loss of support of horizontal structural elements caused by the absence of mechanical connections, overturning of closure external panels due to collapse of the connection with the structure, as well as damage to several non-structural elements.
Particular attention should be therefore paid to the seismic safety of structures constituted of precast elements.

The goal of this Minisymposium is to address several gaps still present in the current literature, concerning the design of precast concrete buildings, seismic performance of existing and retrofitted structures, their numerical modelling, experimental data and life cycle environmental impact, among other aspects.

The Minisymposium aims to collect contributions from researchers, practitioners and manufacturers on the latest advancements in the field of precast constructions. Topics of interest include, but are not limited to, the following:
1. Proposals of new seismic design concepts, for instance related to dowel-based connections;
2. Retrofitting solutions, of the traditional (e.g. concrete jacketing) or innovative type (e.g. dissipation-based interventions);
3. Seismic assessment of existing and retrofitted, single-storey and multi-storey buildings;
4. Local and global modelling strategies;
5. Experimental campaigns;
6. Life cycle environmental impact of buildings and retrofitting solutions;
7. Seismic vulnerability of nonstructural elements typically employed in precast industrial buildings, such as external and internal panels, equipment, supports for gas or liquid distribution systems, racks, electrical cabinets, tanks.

The introduction of engineered wood products (Glulam, Cross Lam, Laminated Veneer Lumber, etc.) has offered new possibilities and encouraged a massive use of timber-based elements in the last decades, making timber-based systems with wide possibilities of use in seismic-prone areas. Moreover, the peculiarities of material sustainability, to be ecofriendly and carbon removal offer high potentialities against the climate changes and for reducing the impact of the construction in urbanised areas. Thus, the excellent seismic response together with their environmental sustainability and energetic efficiency, have stimulated a huge use of timber systems not only in countries particularly devoted to the timber practice (i.e., North America, Japan, Australia, and North Europe) but also in the Mediterranean basin area. In addition to long-span roofs, bridges and floors, timber elements are effectively used to realize highly performing timber structural systems for commercial and residential destinations in seismic zone. Nowadays, studies concerning alternative and innovative uses of timber elements are ongoing by the scientific community. Among these, timber elements used for combined seismic and energetic retrofit of existing masonry and reinforced concrete buildings, innovative connection systems, vertical additions on existing masonry and reinforced concrete buildings, new structural elements, high-rise timber buildings.

Enhancing resilience to earthquake events involves an in-depth understanding and quantification of risk along with a continuous effort to improve the reliability of infrastructure and communities against such hazards. Recent seismic events across the world, including Turkey and Taiwan, stress the need to better understand the interconnections among the experienced regional seismic hazards, the infrastructure’s performance and the community’s ability to prepare, respond, and recover from such disasters. In such complex interactions, several uncertainties need to be addressed at a systems’ level to offer a better understanding of the interventions necessary to achieve a more resilient state. Current efforts extend in multiple directions, including: (1) onsite investigations either in a pre- or post-disaster setting, to record the responses of the infrastructure inventory along with the community’s actions to better understand the impact that such events have, and inform retrofitting and building regulations, (2) use of novel numerical and computational models to better simulate both the hazard and the infrastructure inventory response, in some cases using machine learning and artificial intelligence in order to robustly address the associated uncertainties and (3) community preparedness, such as emergency planning and early warning systems, community response, including rapid damage assessment, and recovery. Such efforts collectively, aim to reinforce the resilience of seismic-prone regions, by better informing them of the different ways that such an imminent disaster can be mitigated fast and with minimal disruptions/fatalities.

This Mini-Symposium aims to promote and share the state-of-the art approaches to reliability estimation for structural systems and their components, along with the quantification of seismic risk, using novel methodologies that aim to improve the resilience of communities against such events.

Earthquakes can cause significant damage to buildings and infrastructure, with subsequent direct and indirect impacts. Several procedures are available to assess and/or design assets to ensure satisfactory levels of seismic safety. However, comparatively fewer procedures also integrate additional society requirements such as environmental sustainability. Moreover, only a few procedures allow considering the exacerbation of impacts due to additional hazards in close temporal proximity to an earthquake. Existing literature on cascading effects shows that the combination of multiple events can lead to higher impacts than the sum of those of the individual hazards. In other words, these multi-hazard scenarios should be integrated into frameworks aimed at quantifying different typologies of impacts, including environmental (e.g., carbon emissions), economic (e.g., replacement costs) and social (i.e., well-being losses) impacts. To tackle the challenges of designing and maintaining structures exposed to multiple events, it is crucial to develop multidisciplinary approaches that integrate these factors into retrofit or new design.

This minisymposium brings together researchers and practitioners to share their expertise in analysing buildings and infrastructure subject to earthquakes and other hazards, paving the way towards a shift in standard approaches to risk modelling. We welcome any application surpassing traditional/conventional practices in earthquake risk modelling, including but not limited to (a) decision-making methods coupling earthquake consequences with other dimensions (e.g., energy cost); (b) multi-hazard risk assessment involving earthquakes as the “primary” hazard and capturing realistic multi-hazard interactions; (c) consequence-based design of new assets or retrofitting. The target audience for this session includes academics, researchers and professionals from various fields, including architecture, civil engineering and sustainability. The session also appeals to policymakers and stakeholders involved in planning, designing and maintaining eco-friendly, safe and resilient systems.

The global priority for a resilient and sustainable built environment is clear. In seismic-prone areas, this means improving seismic safety and energy efficiency while reducing embodied carbon of buildings. Achieving these goals requires adopting resilient technologies to minimize post-earthquake damage and related socio-economic and environmental impacts. These technologies should adopt natural-based materials and plug-and-play systems to reduce construction and demolition waste, considering demolition, recyclability and waste minimization in a circular and life-cycle perspective. Efforts are now increasingly directed towards sustainable building designs for nearly-zero energy or net-zero carbon structures. However, renovating existing buildings in a low-carbon manner also remains a significant challenge, yet essential for driving the development of future-proof, safer buildings that align with current policy targets.

This mini-symposium focuses on the development and implementation of damage-control low-carbon technologies. We welcome applications on innovative solutions, including but not limited to: (a) Integrated design of earthquake-proof and environmentally sustainable technologies for new buildings and retrofitted solutions, encompassing local to global intervention strategies; (b) Experimental studies and/or numerical modeling of resilient structural and non-structural technologies; (c) Case study applications and comparisons with conventional solutions.

Bridge structures are fundamental components for the transportation system of a nation. In many cases, these structures are close to or have already exceeded their design life and an advanced deterioration state can be observed. Deterioration and lack of proper maintenance have been important factors in bridge collapses observed in recent years, as occurred in 2018 for the Morandi Bridge in Italy. As a consequence, the activities of structural management and assessment, together with the definition of advanced maintenance programs, pose a significant challenge to bridge owners. The situation is furthermore complicated by the safety level led by older design codes, which results to be significantly lower than what is provided by modern standards.

The present Mini-symposium aims at promoting the discussion on the challenges that have to be faced in assessing existing bridge structures, also considering the presence of deterioration phenomena, and to share the most recent advances in the assessment and retrofit approaches developed by both the research community and practitioners.

The topics of the Minisymposium include (but are not limited to):

  • Advances in bridge assessment approaches
  • Maintenance, repair and retrofit of existing bridges
  • Numerical and experimental studies on the effects of deterioration on the structural performance

Modern probabilistic risk assessment procedures often require many nonlinear dynamic analyses to consider the (i) inherent aleatory uncertainties in the hazard and (ii) the epistemic uncertainties associated with the exposure and predictive engineering models. In this context, High-fidelity finite element models can faithfully describe the inelastic response, capturing all the essential features of the hysteretic behaviour even for large deformations, thereby supporting high-accuracy risk predictions.

Large numbers of deterministic analyses might become inevitable to fully consider the uncertainties associated with material properties, structural attributes, and seismic hazard. This leads to a high impractical computational cost for routine applications that may be needed to run in real-time for large-scale analyses or emergency management. Consequently, researchers have been incentivised to explore the use of low-fidelity models that approximate the structural behaviour, improving the computational efficiency in various structural dynamics problems, but that also introduce some biases that lead to a reduced degree of accuracy or resolution.

Examples of low-fidelity models considered for earthquake engineering applications include (i) surrogate models, a pure data-driven approximation of the model outputs, and (ii) reduced order models, simplifying the original finite element models condensing dynamic degrees of freedom and simplifying hysteretic response characteristics. While low-fidelity models offer a significant speedup to assessment procedures, the corresponding estimation might be biased when compared to the ones obtained using higher-fidelity numerical models. Therefore, the fidelity of the structural models should strike the right compromise between the accuracy and the computational efficiency objectives. 

This mini-symposium aims to provide a forum for researchers to discuss recent advances and results on low-complexity models to predict the global performance of structures under different types of loading conditions for the computational and structural dynamics community. Relevant topics include, but are not limited to:

  • Calibration of Reduced Order Models (ROM) or Surrogate Models (SM)
  • Techniques or probabilistic frameworks to reduce or adequately account for the biases related to the use of low-fidelity models
  • Validation at the building level or a large geographical scale (with high-fidelity or empirical observations)
  • Applications to different fields of structural dynamics (e.g., seismic, tsunami, debris flows)

Over the past decade, structures and transport infrastructures have faced a number of significant safety issues, which have occasionally resulted in collapses that have had major social and economic impacts. Structural Health Monitoring (SHM) techniques provide a logical solution for the detection of structural deterioration or damage through the assessment of changes in structural characteristics, including displacements, eigenfrequencies, damping factors and mode shapes, using on-site sensors. The recent advancements in interferometric synthetic aperture radar (SAR) processing have significantly enhanced SHM by providing extensive satellite data for monitoring displacement rates of structures over large areas. A significant challenge in SHM is the minimisation of false positives, particularly in instances where minor frequency variations do not indicate actual damage. A substantial proportion of SHM systems focus on the correlation between damage and fluctuations in modal parameters. However, non-stationary inputs (such as wind and traffic) and stochastic environmental alterations can also influence modal parameters. It is therefore appropriate to employ statistical thresholds in order to distinguish between linear non-stationary behaviour and nonlinear structural damage. The objective of this MS is to explore strategies for integrating on-site and remote sensing data, establishing unified damage detection strategies, and discussing advancements in SHM techniques and algorithms. The programme will address a number of key topics, including information integration strategies, signal processing advancements, and case studies on structures, infrastructures, tunnels, dams, and cultural heritage sites.

The design of earthquake-resilient structures has been continuously enhanced in the last years, favouring the adoption of innovative systems and technologies to mitigate seismic effects. To this scope, well-established techniques already available on the market include passive and active vibration control systems based on base isolation and supplemental damping.

A relevant topic is the development of devices and technologies aimed at favouring the re-centring of the structure. Examples include dampers with shape memory alloys, displacement gap devices, rocking systems, and variable friction sliding isolators. Another trend involves the proposal of both isolators and dampers featuring an adaptive force-displacement response and/or implementing an active control. Three-dimensional isolation systems, in parallel / in series combination of devices, and tuned mass dampers with inerters applied to case-studies are also matters that currently attracts interest. New design approaches are profiting of the recent spread of Artificial Intelligence (AI) algorithms.

This Mini-Symposium (MS) aims to draw the interest of academics, researchers, and practitioners, by displaying recent progress in the field of seismic isolation and energy dissipation, and presenting the most recent contributions to the improvement of current technologies for vibration control of steel, RC and masonry structures and infrastructures, as well as timber buildings.

In recent years the scientific community has provided several tools aimed at assessing and managing risk using multi-level and multi-criteria approaches, the latter including the interaction among natural (such as seismic, hydrogeological, volcanic, etc) and anthropic (pollution, nuclear, etc.) risk factors. The trend denotes the rising awareness of the need of a holistic approach for risk assessment, based on the understanding of the factors contributing to the specific risk evaluated that are, as known: hazard (e.g., depending on location, intensity, frequency etc), vulnerability and exposure. In general, these factors may refer to different dimensions and scales. Dimensions may be related, as example, to the structural capacity of construction/infrastructure to withstand hazardous events, the social capacity of a community to recover from a disaster, or the territorial capacity to face the emergency and to allow rapid rescue services in the post-disaster emergency phase. Whereas, the scale refers to the level at which the assessment is conducted, moving from the individual construction/infrastructure/component, up to regions within an entire country. For instance, as for the territorial level, at first qualitative data are required in order to rank the risk by means of a certain resulting score. Then, a ranking list is obtained, from which more refined data and, consequently, more refined numerical simulations may be carried out. To this it should be added that within a multi-criteria framework, risk factors evaluated at different scales pose significative challenges because of their different knowledge domains, often suffering also inconsistencies in terms of methodology and glossary.

This special issue deals with recent advances in the multi-risk field, addressing specifically possible computational strategies for risk evaluation and mitigation focused on existing constructions, both ordinary and cultural heritage ones. Some topics, among the possible ones, relevant to this symposium are:

• simplified and refined multi-level approaches seismic risk assessment, also combined with other risk factors;
• analysis and creation of dynamic inventory reporting the systematic seismic damage suffered after an earthquake;
• statistical analysis of seismic damage and simulation tools;
• structural vulnerability;
• fragility and consequence functions of structural and non-structural components;
• risk-based design procedures for retrofit interventions;
• analyses protection and mitigation against risk;
• expected annual losses (EAL);
• data concerning the effects on the economic system due to hazardous events at large and small scale;
• structural vulnerability and fast appraisal methods.

Nonlinear dynamic analyses are becoming increasingly common in engineering practice to support the vulnerability assessment of existing buildings, structures and infrastructures. A central issue in nonlinear dynamic analyses is damping. Damping in structures refers to the ability of a system or structure to dissipate or absorb energy when subjected to dynamic loads. This can occur in several ways: a) Hysteretic damping, which is implicitly considered in the modeling of the inelastic response of the materials that characterize the structural elements (e.g., hysteresis loops of concrete and steel) when performing a nonlinear analysis (whether with distributed or with lumped plasticity); b) damping resulting from other non-negligible mechanisms such as friction, opening and closing of concrete cracks, thermal energy dissipation due to material heating, and other factors. Damping remains a challenging issues: Its mechanical meaning is still to be fully understood and its numerical modeling has a significant impact on prediction seismic demands on structures.

This Minisymposium aims to collect and discuss contributions focused on damping, both in its theoretical aspects and in applications and modeling.

The prediction of the seismic response is the key issue to bring to light deficiencies and qualities provided by the considered structural systems. This topic is of paramount importance for both new and existing conventional structures, but it becomes even more important when new structural systems or seismic protection devices are developed. On one hand, it is rather obvious that experimental tests, whether dynamic or cyclic tests, provide the most realistic, thus trustworthy, structural response of a considered case study. On the other hand, experimental tests require facilities that are not always available, or can be performed rarely on full scale specimens, but more often on rather small portions of the considered structure or only at component level. Based on this observation, the development of a numerical model represents a practical, as well as easily accessible, alternative to assess the structural response of the considered system. Indeed, numerical analysis can be performed many times, without any economic or material losses, can be used to determine the response of either full scale structures or single structural components, and is the only available tool to conduct wide parametric analysis. However, every numerical model entails unavoidable assumptions and simplifications, that affect the results. Hence, a very effective strategy, which gathers the advantages given by experimental tests and numerical modelling, is to develop numerical models and calibrate the parameters ruling the monotonic/cyclic response of the elements so that the numerical response match as well as possible the experimental one. On one side, this approach allows to develop reliable numerical models that can be used for further extensive analysis, on the other side exploits the realistic response of the experimental tests. The present Minisymposium aims at collecting and discussing contributions focused on (i) the development of numerical models, at building, sub-assembly or member/device level, able to fit the structural response determined by experimental tests, (ii) calibration strategies that can be followed to tune the parameters ruling the numerical model and (iii) possible approaches to evaluate the accuracy of the numerical model in predicting the experimental responses.

Over the past twenty years, the global incidence of natural hazard-related disasters has nearly doubled compared to the preceding two decades. This increase primarily stems from the significant vulnerability of built environments, resulting in escalating impacts on economic and social sectors. Comprehensive assessment and understanding of disaster risks represent the basis for managing the entire cycle, encompassing prevention, forecasting, emergency response, recovery, and fostering adherence to safety-enhancing regulations and standards.

This minisymposium aims to showcase seismic fragility and vulnerability methodologies focused on assessing risk, predicting damage scenarios and ensuing consequences. Various approaches, including empirical methods, analytical or mechanical models will be explored. The discussions will evaluate the strengths and limitations of each approach in terms of their applicability and outcomes. The debate will handle the different methodological approaches and their implications, such as the uncertainty levels associated with different scales of application—whether at the level of individual buildings, at urban level, regional areas, or broader scales. It will also examine how the choice of intensity measures influences fragility assessment outcomes.

The relevant topics to this minisymposium include, but are not limited to:

  • Applicability and results of different approaches for seismic vulnerability and fragility assessment.
  • Impact of using different intensity measures (IM) on fragility assessment, considering the definition of "efficient" and "sufficient" IM, potentially handling also post-earthquake damage data.
  • Effect of stratigraphical amplification in fragility assessment.
  • Uncertainty estimates in fragility results considering the scale of and/or the methodological approach.
  • Influence of aging and deterioration on vulnerability trends.
  • Integration of smart monitoring technologies (remote sensing, UAV) and machine learning in seismic capacity assessment and damage estimation.
  • Effectiveness of shakemap or ground motion prediction equation in forecasting seismic hazard
  • Case studies with a critical discussion about the accuracy level of exposure knowledge, ground motion characterization, and the methodological approach adopted.

Most engineering structures are subjected to a great variety of dynamic loads in their lifetime. The latter can be caused by earthquake, wind, traffic, wave, blast, rotating machinery or other types of natural or anthropic events. The goal of structural engineering is to limit the damage of structures to achieve functional recovery and resilient design. In particular, the need is to meet acceptable performance levels at present and in the years to come without compromising the ability of future generations to use them, maintain them and benefit from them.

In order to achieve such goals, in addition to traditional approaches, structural engineers have introduced sophisticated dynamic response modification techniques and devices. These range from the use of seismic and vibration isolation, to energy dissipation devices, and to rocking isolation. Also, the development and use of new materials with structural capabilities, such as metamaterials and shape memory alloys, are in the forefront.

To guarantee a suitable design of the above-mentioned engineering structures, researchers need to conduct a significant number of experimental tests, required to study and fully understand their actual nonlinear dynamic behavior. They also need to develop accurate and efficient mathematical models and design procedures.

To this end, the aim of the Mini-Symposium is to share the most recent advances related to the complex dynamic response of engineering structures with particular reference to:

  • Experimental Studies: experimental test results describing the nonlinear dynamic behavior of structures, devices, and innovative materials; video-based vibration analysis of structures; experimental verification of numerical methods and mathematical models; experimental calibration of nonlinear model parameters.
  • Mathematical Modeling: solution strategies and numerical methods to perform nonlinear dynamic analyses; mathematical models devoted to simulating the nonlinear behavior of structures and devices; model parameters identification procedures; simulations performed by adopting existing computer programs, such as OpenSees, Abaqus, ANSYS, MIDAS, NextFEM, Sap2000, and 3D-BASIS.
  • Structural Design: design strategies for structures employing linear or nonlinear devices; optimization design methods; case studies of challenging applications.

The use of inertial vibration absorbers to harvest kinetic energy from vibrating structures and structural components and/or dampen structural vibrations has recently captured considerable attention among researchers and practitioners. For small-to-medium scale structural components, piezoelectric-based absorbers coupled with energy harvesting circuitry are widely considered for transforming kinetic energy to usable electric energy, while dampening vibrations. For medium-to-large scale structures, electromagnetic motors commonly interface vibrating structures and energy harvesting circuits to enable kinetic energy scavenging from relatively low-frequency large-amplitude oscillations, sometimes amplified by rotational inerter-based mechanisms. Regardless of the scale and underlying technology, the efficiency of dynamic energy harvesters and inertial dampers relies on robust tuning of their properties in both the mechanical/structural and the electrical/circuit domains, which are heavily dependent on the naturally uncertain attributes of the vibrating structures and the dynamic excitation.

In this context, this Mini-Symposium focuses on the analytic/mathematical modelling, optimal design/tuning, and performance assessment, through simulations or experimental/field testing, of kinetic energy harvesting systems and inertial dampers in the presence of uncertainty to dynamic excitation and/or to system properties. Contributions may discuss mathematical uncertainty modeling aspects for dynamic energy harvesting systems and inertial dampers, computational and analytical methods for assessment and/or design of such systems, and experimental field or lab testing aiming to capture and quantify the behavior of such systems. Both theoretical studies as well as work related to practical engineering problems and focused applications are relevant to this Mini-Symposium. Finally, submissions identifying practical needs and unexplored niches on the development, design, testing, and deployment of regenerative inertial dampers in adverse and uncertain environments are welcome.

Existing steel structures are typically exposed to multiple hazards, including earthquakes, wind and climate change effects. The structural response of such structures is also detrimentally affected by ageing effects which tend to jeopardize the pristine stiffness, strength and ductility and, in turn, their energy dissipation capacity. Current codes of practice worldwide provide simplified approaches for the structural assessment of existing steel structures; these code provisions exhibit a number of limitations for applications, especially for structural systems with ageing effects. Thus, there is an urgent need of robust and refined assessment methods to evaluate the structural performance of existing steel structures, plus quantify reliably financial losses. Accurate local response analysis for existing steel systems, e.g. including refined modelling for base-to-column and/or beam-to-column connections designed for gravity-loads only, requires further numerical and experimental investigations.

Current assessment approaches are extensions of methods developed and corroborated for newly designed structures. Furthermore, they are often not adequately calibrated for existing steel systems, especially for those with corrosion and other deterioration effects (stiffness, strength, etc).

Experts in the field of existing steel structures, especially those systems that are not conforming to modern design standards, are invited to contribute to this MS. Emphasis is on the limitations of current approaches for structural response analysis, plus proposing possible adaptations and identification of challenges to foster future experimental and numerical investigations. Use of advanced techniques of machine learning and AI-based methods to replace time-consuming experimental tests is also relevant for the MS.

Finally, the MS intends to discuss state-of-art techniques for structural retrofitting for existing steel structures and proposing a roadmap for sustainable and resilient interventions.

According to the capacity design requirements, earthquake resistant structures have the ability to dissipate energy in plastic mechanisms. Dissipative zones are designed to yield before others, that remain in the elastic range during the seismic action. The capacity design approach allows for a reduction of seismic forces through the seismic behavior factor, as it is assumed that dissipative elements yield and dissipate energy. The reduction of seismic actions involves a reduction in dimensions of structural members and therefore in the cost of the structure. Simultaneously, recent advanced dissipative devices are developed with the aim of ensuring an adequate dissipation of energy, provide stable hysteresis loops and, according to the Loss-Based Design, to be easily replaced after a seismic event. The minisymposium encourages the submission of research papers dealing with adopted/developed fuses of earthquake resistant steel structures, investigated through experimental tests, numerical models and analytical methods.

Topics relevant to this minisymposium include, but are not limited to:

1) Seismic protection devices for earthquake resistant steel structures;

2) Innovative fuses capable of dissipate energy through stable hysteresis loops;

3) Numerical models, experimental tests and analytical methods to simulate the structural response of investigated devices;

4) Novel steel bracing systems.

Experience and research developments have led to significant advances in the subject of seismic engineering over the past years. In the particular field of seismic design, the development and revisions of a new generation of design codes such as the Eurocode 8 is an important milestone. Although this code still promotes the use of classical seismic design approaches deeply imbedded in current practice, e.g. force-based approaches considering the use of behaviour factors (q-factors) and enforcing capacity design principles, Eurocode 8 also encourages the use of more advanced methods of analysis. Although the core of such analysis methods, i.e. nonlinear static and nonlinear dynamic analysis methods, can be seen as reasonably well established, several developments and studies are still needed from the practical use and design process point of views. Namely, an adequate safety format, similar in scope to the one involving linear analysis methods, is yet to be explicitly addressed in a framework which foresees the use of nonlinear analysis methods. Papers that address this thematic are welcome, namely on the following specific fields: nonlinear dynamic analysis; seismic input; structural safety assessment methodologies; experimental characterization of structural elements under cyclic loadings; case studies.

Nonstructural elements (i.e., architectural elements, mechanical/electric/electrical/hydraulic systems, and building contents) are extremely vulnerable to seismic damage and are associated with critical exposure. The definition of their seismic performance is still an open issue within the international community. Evaluating seismic response and capacity of nonstructural elements involves experimental testing, analytical modelling, and numerical simulations, and advanced studies are needed to quantify their potential impact on the overall seismic risk associated with the hosting building. A proper design and assessment of nonstructural elements accounting for their seismic response can significantly reduce seismic risk, ensuring occupant safety, and minimize post-earthquake repair costs and downtime.

We invite contributions that explore various aspects of the seismic response, capacity, and performance evaluation of nonstructural elements, including but not limited to (a) experimental testing, (b) analytical modelling and numerical analysis, (c) design and assessment procedures and code-related aspects, (e) case study applications, (f) comprehensive and large-scale implementation, and (g) structural to nonstructural interaction problems.

Nonlinear response history analysis (NRHA) stands at the forefront of seismic performance assessment methods in structural engineering, utilizing acceleration time histories for precise numerical simulations. A primary challenge lies in accurately modeling seismic excitations. To ensure effective seismic analysis and design, acceleration time histories must faithfully represent the site's seismicity and anticipate expected or design earthquake scenarios, encompassing all potential future events.

Ground motion record selection involves scaling recorded ground motions or generating synthetic and simulated databases. Despite the widespread availability of large ground motion databases, challenges persist in applying NRHA in engineering contexts. Real records often originate from locations different from the site under consideration, introducing variations in hazard scenarios. Additionally, obtaining records of large earthquakes necessary for studying ultimate limit states, such as collapse, remains challenging. Ground motion databases primarily consist of small-to-moderate events, complicating comprehensive performance-based assessments, particularly in regions lacking recordings of large-magnitude earthquakes at small epicentral distances or on soft soil conditions.

To address these challenges, engineers frequently scale ground motion amplitudes to align with targeted seismic hazard scenarios, typically represented by specified acceleration spectra or ground motion models. However, scaling introduces potential biases that may systematically under- or overestimate actual structural responses. Effective record selection algorithms can help mitigate these biases. Recent advancements have also focused on utilizing ground motion simulations in engineering applications, which is particularly beneficial for regions with limited recorded data. This approach reduces dependence on scaling methods for areas with sparse ground motion recordings, thereby enhancing the reliability of seismic assessments.

This minisymposium aims to convene researchers from engineering seismology and earthquake engineering to discuss advancements in techniques for selecting and scaling real or simulated ground motion records in engineering practice along with their practical applications without biasing response estimates. Topics to be covered include:

  • Innovations in ground motion selection and scaling techniques
  • Generation of artificial acceleration time histories
  • Heuristic approaches and algorithms for record selection
  • Multi-objective optimization techniques
  • Automated and semi-automated procedures in ground motion analysis
  • Integration of machine-learning methodologies
  • Code spectra, uniform hazard spectra, and conditional mean spectrum
  • Case studies and practical applications

By facilitating collaboration and knowledge exchange, the minisymposium seeks to advance methodologies that improve the accuracy and reliability of seismic performance assessments in structural engineering, contributing to safer and more resilient built environments.

Many structures and infrastructures across Europe are approaching their service lifespan with an accumulation of degradation to several structural elements due to aging and poor maintenance actions. These latter consist in reinforcement corrosion to primary members like deck and piers as well as degradation of bearing devices, regarding both bridges and buildings structures. Usual assessment methodologies adopted in the practice, often neglect the presence of damage and degradation happened to these members, leading to an incorrect risk evaluation with respect to both static and dynamic loads. Therefore, it is necessary to characterize the degradation phenomena, which must be accounted for in the assessment phase of structures and infrastructures in order to get a more reliable evaluation of risk at an individual level, giving the opportunity of a more effective prioritization of interventions at regional scale. Hence, this MS wants to collect results of experimental campaigns for the evaluation of the residual capacity of degraded members and bearings and conclusions about their modelling issues as part of a whole construction. Furthermore, numerical simulations of case studies buildings and bridges, where degradation of structural members and bearings has been explicitly considered, are welcome.
