A collaborative Bayesian optimization method for estimation of failure probability bounds under mixed uncertainties
Wei, Pengfei; Beer, Michael; Faes, Matthias; ICASP14; Valdebenito, Marcos; Song, Jingwen; Hong, Fangqi (2023)Uncertainty quantification has been realized as of vital importance in structural reliability engineering to achieve credible results especially when the available information is scarce, incomplete, imprecise, etc., and ... -
Approximate Bayesian Computation considering Summary Statistics for Parameter Identification in Computational Mechanics
Misraji, Mauricio; Faes, Matthias; Valdebenito, Marcos; ICASP14; Pauly, Markus; Klein, Nadja (2023)Computational mechanics offers the possibility to construct numerical models that simulate the behavior of real-world engineering systems. These numerical models usually depend on a series of parameters such as material ... -
Estimation of failure probability function and its bounds under random and interval variables: A fully decoupled approach using Bayesian active learning
Liu, Jinxing; Beer, Michael; Valdebenito, Marcos; ICASP14; Faes, Matthias; Dang, Chao (2023)Random and interval variables can coexist in a single structural reliability analysis problem. The existing methods for such hybrid reliability analysis, however, cannot balance the computational cost and accuracy well. ... -
First Excursion Probability Sensitivity Estimation by means of Multidomain Line Sampling
ICASP14; Beer, Michael; Jerez, Danko; Misraji, Mauricio; Faes, Matthias; Valdebenito, Marcos (2023)The first excursion probability offers the means for measuring the chances that one or more dynamic responses of a structural system subject to stochastic loading exceed a prescribed threshold level within a certain time ... -
Uncertainty Quantification of Buckling Loads of Thin and Slender Structures Applying Linear and Nonlinear Analysis
Faes, Matthias; Freitag, Steffen; Fina, Marc; Beer, Michael; Broggi, Matteo; Wagner, Werner; ICASP14; Valdebenito, Marcos (2023)The evaluation of the buckling load is a crucial issue when designing different types of structures. It is well known that buckling loads of structures are highly sensitive to random deviations from a nominal design, which ...
