Research on the Pushover Methodology and the Applications on the Bridge Seismic Performance Improvement Scenarios

Abstract

Abstract-In this paper, we conduct research on the pushover methodology and the applications on the bridge seismic performance improvement scenarios. Bridge is an important part of the traffic lifeline engineering, and after the earthquake, if the bridge damage, that will hinder the timely disaster relief operations, increase secondary disasters, not only cause the direct or indirect losses of people's life and property, also affect the post-disaster recovery and reconstruction. Therefore, seismic design of the bridges has been people's attention. From the earthquake when the bridge failure mechanism and the failure process point of view, to adjust the overall layout design of bridge structure, fundamentally improve the structural seismic performance as a whole. Our research proposes the novel paradigm for the corresponding challenges that will be meaningful.
