Cross-Entropy-Based Adaptive Concurrent Importance Sampling for Probabilistic Seismic Loss Analysis of Spatially Distributed Multistate Systems

Abstract

AbstractSpatially distributed infrastructure systems are crucial assets of a community, and thus assessing their risk under seismic hazards is essential. These assessments should be system-wide, regional, and probabilistic to provide comprehensive ...Practical ApplicationsThis study introduces a sampling-based approach to improve the computational efficiency of seismic risk and loss assessment at both the network and regional scales. We propose a cross-entropy-based concurrent adaptive importance ...
