MS03: Uncertainty Modeling and Quantification for Model Updating and Structural Health Monitoring
Abstract: Structural Health Monitoring (SHM) aims at condition assessment and service life monitoring of structural systems, often based on the availability of system vibration data. Model updating has been developed as a key technique for SHM, where the parameters or the numerical model itself are calibrated to tune the model prediction close to the actual system behaviour. However, uncertainties are inevitable in both the measuring and modeling processes, which leads to the necessity of non-deterministic approaches to modeling and quantifying the uncertainties. This Mini-Symposium is dedicated to gathering experts from both academia and industries to showcase the latest advances on the uncertainty treatment in model updating and SHM and their practical applications.

  • Topics for potential contributions include but are not limited to:
  • Stochastic/interval model updating;
  • Inverse quantification of mixed aleatory and epistemic uncertainty;
  • On-line model updating for nonlinear dynamic systems;
  • Model updating and SHM applications in large-scale structures.

MS05: Stochastic finite element methods and their applications on model updating
Abstract: Stochastic finite element method is an important tool widely used in many aspects such as reliability analysis, safety assessment and model updating et al. At present, various stochastic finite element methods have been developed. As typical representatives among these methods, the perturbation methods and the Garlekin based methods like PC and GPC, have been successfully applied to solve the stochastic problems in extensive industrial fields. However, highly accurate and efficient stochastic finite element methods are still developing to implement the stochastic analysis of large-scale structural models. This research direction has been attracting many researchers’ attention.

Model updating is a key content in structural health monitoring. When considering the randomness of structural modelling and measurement data, the stochastic model updating becomes unavoidable. To solve stochastic model updating problems, the stochastic finite element methods can play a significant role instead of the usually used Bayesian methods. This direction is a hot topic in current structural model updating, which has a very good application prospect in practical structural health monitoring.

The symposium aspires to create a conducive environment for scholars, researchers, and practitioners to exchange insights and findings, fostering collaborative endeavors and innovations in the domain of stochastic finite element method. The inclusion of diverse theoretical explorations and practical applications is anticipated to provide a comprehensive perspective on the evolving role of stochastic finite element method to address the inverse problem in health monitoring.

Topics for potential contributions include but are not limited to:

  • Recent advances in stochastic finite element method.
  • Advanced computational techniques in Stochastic Static and Dynamics.
  • Recent mathematical and numerical developments in stochastic structural engineering static and dynamics.
  • New surrogate modeling techniques tailored to some computationally-demanding problems.
  • Stochastic finite element method in reliability analysis, safety assessment.
  • Stochastic model updating.
  • Model update with structural health monitoring.
  • Engineering practice of structural health monitoring accommodating uncertainties.
  • Novel uncertainty quantification techniques in model updating.
  • Data-driven approaches for model updating.

MS08: Data-driven and Uncertainty-aware Modeling of Complex and Nonlinear Systems
Abstract: The recent years have seen significant progress in modeling complex and nonlinear systems, with a notable shift towards data-driven methodologies and a heightened recognition of the inherent uncertainties associated with such systems. Non-deterministic modeling approaches, including probabilistic, interval, fuzzy, or imprecise methods, necessitate accurate specification of uncertain model parameters. However, direct measurement of these quantities is often impractical or cost-prohibitive, leading to the widespread application of data-driven and uncertainty-aware modeling techniques.

This mini-symposium aims to bring together experts, researchers, and practitioners from academia and industry to explore and discuss the latest developments, methodologies, and applications related to data-driven modeling and the incorporation of uncertainty-aware techniques in understanding complex and nonlinear systems. Papers discussing advances in techniques from both uncertainty forward and inverse propagation by probabilistic theory, as well as interval methods and concepts based on imprecise probabilities are invited. Next to these non-deterministic and data-driven approaches for numerical modelling, stochastic model updating, system identification, damage localization, sensor placement optimization is highly welcomed.

Topics for potential contributions include but are not limited to:

  • Stochastic model updating
  • Highly efficient uncertainty propagation
  • Quantification of multiple uncertainty sources
  • Data-driven modelling
  • Imprecise probability
  • System identification
  • Sensor placement optimization
  • Digital twin

MS09: Addressing Aleatoric and Epistemic Uncertainty with Imprecise Probabilities
Abstract: Uncertainties appearing in engineering problems can be broadly classified as aleatoric and epistemic. The first group refers to intrinsic uncertainty stemming out of randomness, while the latter reflects lack of knowledge, conflicting sources of information, etc. One possibility for tackling such class of problems is resorting to imprecise probabilities which, in essence, can be interpreted as a collection of classical probabilistic models that account for aleatoric uncertainty and which are indexed by, e.g. interval variables that capture epistemic uncertainty. Although imprecise probabilities offer an extremely wide and flexible framework, its practical deployment is not devoid of challenges. Therefore, the aim of this MS is bringing together some of the latest developments on imprecise probabilities, including (but not limited to):

  • Different models for representing uncertainty such as, e.g. p-boxes, imprecise stochastic processes, distribution-free models, etc.
  • Novel formulations for coping with aleatoric and epistemic uncertainty, such as advanced simulation methods; surrogate models, etc.
  • Inverse uncertainty quantification in the presence of aleatoric and epistemic uncertainty.
  • Practical applications involving challenging engineering problems.

MS14: Global Reliability Analysis of Complex Nonlinear Stochastic Dynamical Systems
Abstract: The study of complex nonlinear stochastic dynamical systems is of paramount importance in both science and engineering. These systems exhibit a myriad of uncertainties, stemming from various sources such as material properties, external excitations, and inherent nonlinearities. These uncertainties introduce significant ambiguity into the response of systems, making precise analysis and design a formidable challenge. The coupling of nonlinearity and stochasticity necessitates a refined understanding of uncertainty propagation, which is indispensable for ensuring the safety and reliability of engineering systems. This symposium invites you to contribute to the discussion on the complexities of global reliability analysis in engineering structures. We welcome contributions that address, but are not limited to, the following themes:

  • Novel approaches for modeling and analyzing complex nonlinear systems subjected to stochastic influences.
  • Techniques for addressing the safety challenges associated with high-dimensional uncertainty inputs in engineering systems.

  • Innovative strategies that combine physical understanding with data-driven approaches for more robust reliability analysis.
  • Techniques for precisely assessing low failure probabilities under rare events, critical in high-consequence systems.
  • Effective and efficient reliability methods in the context of reliability-based design optimization of complex nonlinear stochastic dynamical systems.
  • optimization of complex nonlinear stochastic dynamical systems.
  • We strongly encourage and warmly welcome contributions that address real-world applications and propose pioneering theories within disciplines such as civil engineering, aerospace engineering, construction engineering, mechanical engineering, energy engineering, automotive engineering, and other relevant fields.
