Maximum entropy-based modeling of community-level hazard responses for civil infrastructures
Xiaolei Chu, Ziqi Wang
Perturbed by natural hazards, community-level infrastructure networks operate like many-body systems, with behaviors emerging from coupling individual component dynamics with group…
Efficient seismic reliability and fragility analysis of lifeline networks using subset simulation
Dongkyu Lee, Ziqi Wang, Junho Song
Various simulation-based and analytical methods have been developed to evaluate the seismic fragilities of individual structures. However, the seismic safety and resilience of a co…
A physics and data co-driven surrogate modeling method for high-dimensional rare event simulation
Jianhua Xian, Ziqi Wang
This paper presents a physics and data co-driven surrogate modeling method for efficient rare event simulation of civil and mechanical systems with high-dimensional input uncertain…
Adaptive active subspace-based metamodeling for high-dimensional reliability analysis
Jungho Kim, Ziqi Wang, Junho Song
To address the challenges of reliability analysis in high-dimensional probability spaces, this paper proposes a new metamodeling method that couples active subspace, heteroscedasti…
Relaxation-based importance sampling for structural reliability analysis
Jianhua Xian, Ziqi Wang
This study presents an importance sampling formulation based on adaptively relaxing parameters from the indicator function and/or the probability density function. The formulation…
