A two-level Kriging-based approach with active learning for solving time-variant risk optimization problems
H. M. Kroetz, M. Moustapha, A. T. Beck +1
Several methods have been proposed in the literature to solve reliability-based optimization problems, where failure probabilities are design constraints. However, few methods addr…
Replication-based emulation of the response distribution of stochastic simulators using generalized lambda distributions
X. Zhu, B. Sudret
Due to limited computational power, performing uncertainty quantification analyses with complex computational models can be a challenging task. This is exacerbated in the context o…
Surrogate-assisted reliability-based design optimization: a survey and a new general framework
M. Moustapha, B. Sudret
Reliability-based design optimization (RBDO) is an active field of research with an ever increasing number of contributions. Numerous methods have been proposed for the solution of…
Uncertainty propagation of p-boxes using sparse polynomial chaos expansions
Roland Schöbi, Bruno Sudret
In modern engineering, physical processes are modelled and analysed using advanced computer simulations, such as finite element models. Furthermore, concepts of reliability analysi…
Characterization of random stress fields obtained from polycrystalline aggregate calculations using multi-scale stochastic finite elements
Bruno Sudret, Hung Xuan Dang, Marc Berveiller +2
The spatial variability of stress fields resulting from polycrystalline aggregate calculations involving random grain geometry and crystal orientations is investigated. A periodogr…
Assessment of the lognormality assumption of seismic fragility curves using non-parametric representations
Bruno Sudret, Chu Mai, Katerina Konakli
Fragility curves are commonly used in civil engineering to estimate the vulnerability of structures to earthquakes. The probability of failure associated with a failure criterion (…
