Abstract
When steel arch bridges are subjected to fault displacement, seismic performance and damaged mechanism of steel arch bridges have not become clear yet. This paper presents the results of pushover analyses and nonlinear dynamic analysis of half through steel arch bridge subjected to fault displacement in transverse, vertical and longitudinal directions, and clarifies the effect of fault displacement on the evaluation of seismic performance of half through steel arch bridges. The pushover analysis of half through steel arch bridge by displacement control method was carried out, then followed the nonlinear dynamic analysis in order to investigate seismic performance and ductility of this bridge. The validity and effectively of a dynamic verification method for half through steel arch bridge subjected to Level 2 ground motion was discussed.
