This study presents an analysis of the seismic response characteristics and seismic performance of arch concrete bridge. Nonlinear analysis using three-dimensional analytical model was conducted considering 18 modified ground motions. A linear analysis was applied to observe the dynamic response characteristics for the arch bridge after dampers installation. Finally, the damper location effect on the bridge seismic response was studied using a linear analysis.
