Performance based design must evaluate the phenomena precisely and stipulate the conditions of bridge in consideration of performance and safety of bridge system. Under the simulation of a large earthquake, it is essential to define how much damages can be acceptable to each component of bridge and how far its energy sharing can be expected, which enable the seismic design to secure safety throughout the bridge system. Each component of a bridge system such as bridge pier, girder, bearing, abutment of a bridge, in some cases, absorb energy due to a partial damage of materials, concrete cracks and elasto-plastic behavior of steel. While even without damages some can absorb energy repeatedly by installing damping device such as seismic isolation bearing. This study , targeting a bridge system composed of bridge pier, girder，bearing and abutment of a bridge, focused on abutment which can easily secure large reaction force compared with bridge pier generally installed with seismic isolation bearing and can secure sufficient space for installing dampers and others. In this study dynamic response analysis of a bridge with dampers on its abutment has been conducted and dampers performance has been assessed with view to securing rational seismic safety of a bridge system.
