Post-earthquake functionality assessment of subway stations considering the interdependency among sub-systems

This study proposes a framework for the post-earthquake functionality assessment of subway stations, in which the effects of seismic damage of components and interdependency among sub-systems are considered by combining the fault tree analysis and Bayesian network method, and the post-earthquake functionality is quantified by combining multi-agent simulation and simulation optimization methods. The effectiveness of this method is verified based on a numerical study of a typical subway station. The proposed framework can assist stakeholders of subway stations to systematically assess the functional performance of the system under different earthquake levels and provide support for the design and post-earthquake emergency management of subway stations.
