Evaluation of Seismic Reliability of Steel Bridge Piers Considering Energy Absorption Performance

Abstract

In this study, the seismic response characteristics of steel pier subjected to earthquake load are clarified by the time-history elasto-plastic response analysis method. And a seismic reliability evaluation method of steel pier considering the energy absorption performance is proposed. Through of some numerical calculations, the relationship between the energy absorption performance and damage index is examined, and then both effects of the geometrical shape and the flexural stiffness of longitudinal stiffeners on the seismic reliability index of steel pier are evaluated.
