Elastic-Plastic Analysis of Seismic Performance for Bridges with Corrugated Steel Webs

Abstract

This paper examines a corrugated steel web prestressed concrete (PC) continuous box girder bridge constructed in China. Finite element analysis was employed to simulate the structure, and the seismic response of the bridge was calculated using elastic time-history and elasto-plastic time-history analysis. The analysis results indicate that, when using a plastic hinge model to simulate the pier, the pier undergoes bending into a plastic state under E2 seismic conditions, reaching the first yield state longitudinally and exhibiting slight plasticity laterally. These findings provide technical support for the design and construction of similar bridges in the future
