海报摘要

Structural reliability analysis aims to estimate the probability of failure, considering various sources of uncertainty. Among the existing reliability analysis methods, surrogate modeling-based active learning methods are gaining increasing popularity due to their excellent trade-off between accuracy and efficiency. This work focuses on developing an efficient algorithm to terminate the active learning process at an appropriate stage. Specifically, we derive an error-based stopping criterion (ESC) using Chebyshev’s inequality. This criterion allows for the easy calculation of the upper bound of the estimation error for failure probability, without making any assumptions or resorting to bootstrap resampling analysis (BESC). Furthermore, we develop a hybrid stopping criterion that considers both the estimation error of failure probability and its stabilization property at the converged stage. This criterion aims to enhance the computational efficiency of active learning methods. We demonstrate the applicability and effectiveness of the proposed approach through several numerical examples with varying complexity.
