Modeling time-dependent behavior and deterioration of concrete

In recent years, topics such as robustness, resilience, sustainability, life-cycle assessment have shifted into the focus of engineering societies. Many concepts have been developed. Yet, accurate and physically based prediction models and modeling concepts for the time dependent behavior and deterioration of concrete, which are quintessential inputs, are still scarce. This Mini‑Symposium will provide a forum for international experts and researchers to discuss recent developments in modeling time-dependent phenomena relevant to concrete structures. In particular, authors working on research related to creep and shrinkage, alkali-silica reaction, delayed ettringite formation, carbonization, freeze and thaw, corrosion, sulphate attack, and the age-dependent change of mechanical properties are encouraged to submit abstracts. Further topics of interest include coupled problems such as e.g. cracking damage and permeability or transport processes in ageing and deteriorating concrete structures.

Instabilities and Bifurcations in Solids, Structures and Soft Materials

Extreme materials and structures such as soft matters, thin films, biomembranes and slender rods, are often at the heart of modern technologies, and their studies have implications and applications in many areas ranging from biology, electronics manufacturing, civil to biomedical engineering. A basic characteristic of such extreme materials is their ability to experience large displacement, rotation and deformation under multiple fields, which inevitably leads to formation of patterns that are much more varied and complicated than those in traditional materials. Such pattern formation is often the result of multiple bifurcations or loss of stability. Knowledge on how such instabilities arise and evolve is essential to describe, understand, predict, and ultimately to design complex materials and structures in modern industry, for example micro/nano-scale surface patterning control. This requires advanced theories, computational and experimental techniques. We hope to bring together experts working on these different aspects to review and share the latest advancements in this vibrant research field. Topics of particular interest include but are not limited to:

- geometric and material instabilities in soft materials such as gels and liquid crystalline polymers.

- wrinkling, creasing, folding and ridging in biomaterials under various stimuli.

- shape buckling of flexural structures such as plates, shells and membranes.

- mechanical self-assembly of ordered patterns via spontaneous surface wrinkling of soft materials and their applications in the development of advanced materials, including advanced functional surfaces and soft metamaterials.

- applications of pattern formation in soft materials to the development of novel flexible devices.

Computer Vision-based Studies in Structural Health Monitoring

It is generally accepted that computer vision will drive the next revolution in information and artificial intelligence. Furthermore, due to the recent advances in sensor technology and computational capability of computers, the use of vision-based approaches for condition assessment of structures provides an unprecedented opportunity to improve the resilience of structural systems. Moreover, these approaches are contactless and appropriate to be incorporated in mobile sensing robots such as unmanned aerial vehicles. This mini-symposium will provide the opportunity to discuss recent theoretical, computational and experimental advances in using computer vision and machine learning approaches for structural identification, control and health monitoring. Topics relevant to this session include, but not limited to, data collection and analysis, damage detection, classification, quantification and localization, change recognition, displacement and dynamic measurements, deep learning, convolution neural networks, sensor calibration, fusion and optimization, scene reconstruction, activity monitoring, and new emerging vision-based technologies.

Nonlinear stochastic structural dynamics methodologies for complex engineering systems

It is vital to bear in mind that in real structural and mechanical systems nonlinearities arise in various forms, and usually become progressively more significant as the amplitude of vibration increases. This fact brings to the fore the need for a more pertinent representation of the system model by considering thoroughly the real mechanisms which determine to a great extent the overall system behavior. In this setting, a suitable stochastic representation of the induced excitation in conjunction with nonlinear system modeling provides a solid and rigorous basis for response system determination and reliability assessment. Clearly, persistent nonlinear stochastic structural dynamics problems faced by engineers of practice are amenable to efficient and comprehensive solutions, harnessing the potential of recent advances in broad reaching topics such as inelastic random vibration theory, stochastic hazard modeling and Monte Carlo simulation-based approaches.

The objective of this MS is delineated in the discussion of current and emerging approaches for modeling and analysis of nonlinear stochastic dynamic systems. Further, this MS intends to provide a forum for fruitful exchange of ideas and interaction among diverse technical and theoretical disciplines. Specific topics related both to fundamental research and to practical applications of nonlinear stochastic dynamics will be considered.

Damage modelling of engineering structures

Starting with localized cracking and ending with structural collapse, the progressive failure of engineering structures is usually governed by damage evolution in different levels. To this end, theoretical models and numerical methods for predicting the damage behaviour of structures play increasingly important roles in the design of structures, although their current status lag far behind engineering practices. This symposium aims to promote collaborations among academic researchers and industrial engineers in developing and applying damage models and related numerical methods to the prediction of nonlinear behaviour of engineering structures. Those who have been working on related fields are cordially invited to exchange their ideas and research outcome in this mini-symposium.

Non-deterministic modelling and uncertainty management in structural dynamics and vibroacoustics

It is widely recognized that the unavoidable appearance of uncertainties in both operational experiments and approximately numerical analyses requires efforts to be dedicated in the tasks of model updating, verification, and validation. Non-deterministic modeling approaches enable characterization, propagation, and quantification of the inevitable uncertainties, providing predictions over a possible range of outcomes (interval, distributional, fuzzy, etc.) rather than a unique solution with maximum fidelity to a single experiment. Such approaches applied in structural dynamics significantly promote the tendency towards high accuracy and robustness in computer-aided engineering.


Compared with structural dynamics, vibroacoustics is a challenging application domain for non-deterministic modeling because of the severe lack of knowledge in the coupling mechanism between structures and fluid environments. Thus, it requires further development of the current techniques for uncertainty treatment to enhance the trustworthiness of computational mechanics engineering.


The scope of this mini-symposium is to bring together academic researchers and practicing engineers concerned with the various aspects of non-deterministic modeling and uncertainty management on the application of both structural dynamics and vibroacoustics. Contributions addressing developments in the theoretical, and computational approaches as well as practical applications are invited, such as stochastic model updating, model validation, experiment modal analysis, modal identification, noise and vibration controlling, and uncertainty quantification with Bayesian approaches, interval models, fuzzy techniques, etc.

Reliability analysis of engineering structures under disastrous excitations

The objective of this MS is to report recent advances and emerging approaches related to reliability analysis of large-scale engineering structures under disastrous excitations. For engineering structures, it is almost inevitable to encounter nonlinear behaviors when they are driven by disastrous excitations, e.g. seismic ground motions, hurricane and grand waves. The failure mechanism is typically different from the static one, which is of significance to formulate the corresponding limit state function for reliability considerations. On the other hand, randomness has long been observed and widely recognized in both disastrous excitations and structural parameters. The modelling of disastrous excitations is also of paramount importance to comprehensively understand the structural behaviors. Usually, the disastrous excitations are modelled as stochastic processes and the uncertain structural parameters are modelled as random variables. In this regard, the reliability assessment could be performed on the basis of stochastic dynamics of structures. Although the reliability (or stochastic dynamic) analysis of linear structural dynamic systems has been well-developed, the reliability analysis of nonlinear structural dynamic systems considering the randomness in both excitations and structural parameters is still an open challenge, especially when a large number of random variables are involved. Specific contributions related to both methodology developments and engineering applications regarding but not restricted to following aspects are welcome:


(1). Failure mechanism of structures under disastrous excitations

(2). Modelling of disastrous excitations

(3). Techniques for stochastic dynamics of structures

(4). High-dimensional reliability methods

Dynamic analysis and seismic performance of structures under strong earthquake ground motions

Since the several 1990s great earthquakes causing severe structural damage or collapse (such as the 1994 Northridge, California and the 1999 Chi-Chi, Taiwan, earthquakes), the dynamic response analysis and seismic performance of engineering structures (buildings, bridges, dams and tunnels etc.) under strong earthquake ground motions including near-fault motions and long-period ground motions is the important research topic in the community of earthquake engineering and mechanics.

In general, near-fault ground motions possess distinct characteristics different from those of far-fault ground motions, which have been attracting more and more attention. The forward directivity effect,  fling-step effect, hanging wall effect and vertical component effect etc. at rupturing fault are the widely concerned effects, in which the former two effects lead to the long-period impulsive ground motions. On the other hand, the certain path effects and site effects can cause the far-fault long-period ground motions (e.g., 1985 Mexico earthquake, 2004 Niigata-ken Chuetsu earthquake), which also impose great damage to high-rise buildings and long-span bridges and so on.

Numerical modeling, seismic performance analysis and damage control of structures under strong ground motions are imperative. This mini symposium mainly covers the following research aspects:

(1) Engineering characteristics of near-fault motions and long-period ground motions etc.;

(2) Advanced time integration algorithms and computational methods in structural dynamics;

(3) Efficient modeling techniques of large-scale engineering  structures;

(4) Random vibration analysis and dynamic reliability assessment of various structures;

(5) Seismic performance analysis and safety evaluation of structures;

(6) Damage reduction and vibration control techniques and performance analyses of structures.

Uncertainty Quantification and Reliability-based Performance Evaluation


As the future occurrence of stressors and extreme events, and the evolution of structural components’ deterioration cannot be deterministically predicted, uncertainties and risks in engineering are involved to a greater extent than ever before. So that, reliability and performance analysis become increasingly complicated due to uncertainties and complexity.  Advanced random-variable-based and random-process-based uncertainty analysis methods have significant developed in recent years. However, structural performance analyses of structures become complicated under the condition of complex uncertainty. This has addressed significant challenges on the study of reliability-based performance analyses.

Overall, uncertainty quantification and reliability-based performance evaluation have received much attention in the civil, mechanical, and aerospace engineering communities over the past decades. This Mini-Symposium will bring together engineers and scientists of all kinds from across academic, industrial and governmental institutions who face uncertainties in their modelling, simulation, assessment and design problems, and aims at promoting scientific development and innovative application of reliability-based, risk-based, or other uncertainty-informed performance evaluation methods to address all safety related aspects in the management of engineering systems.
