Abstract

In order to clarify the effects of earthquakes and EISE on resilience of highway bridge networks, a resilience analysis method was proposed, which considered factors like regional seismic hazards, characteristics of EISE, structural fragility of bridges and traffic characteristics, etc. Subsequently, response mechanism to EISE was analyzed, based on which EISE influence model on highway bridge network was established, and a method to analyze the network state under influence of both earthquakes and EISE was proposed. Finally, several resilience indexes were developed, and verification was conducted on a highway bridge network in San Francisco, California subjected to both earthquakes and EISE effect. The results show that compared with individual bridges, the performance of bridge network was influenced by interaction between earthquake motion and EISE, including not only the intensity, but also locations of earthquakes. And the proposed methodology can assess resilience of bridge networks against EIES. © PHYSOR 2022 China Safety Science Journal. All rights reserved.
