After the 1995 Kobe strong earthquake, it has been greatly revised in Japanese highway bridge codes. It was secured a large gap size of the girder for the collision of girders by the Level 2 Earthquake Ground Motion of the seismic design. However, if a large gap size of the girder is adopted, the expansion joint have to be largely changed. Furthermore, the construction costs and the seismic reinforcement costs will be increased. It was considered that the gap reduction allowing the collision of girders, as a premise of preventing the collapse of the bridge, was one of the seismic reinforcement method in order to decease the construction costs and the seismic reinforcement costs. In addition, it is necessary that damage of the girder end and the pier bottom is decreased by attaching rubber shock absorber to the end of girder. In order to reduce gap size between girders, it is necessary that the resistance characteristics of the abutment due to the collision of girders and the dynamic response characteristics due to the damping at the bottom of pier are grasped. Although many studies on the collision phenomenon of bridge girders have been published, the effects of cost on seismic reinforcement allowing the collision of PC bridge girders have not been sufficiently considered yet. In this study, the resistance characteristics of the abutment due to the collision of girders and the dynamic response characteristics due to the damping at the bottom of pier will be verified by carrying out dynamic response analysis that the 3-dimensional finite element model (3D-FEM) of the PC bridge was built. In addition, the effects of cost on the proposed seismic reinforcement allowing the collision of concrete bridge girders will be considered. From the comparison of the total cost on both the current method and the proposed one, it will be confirmed that the proposed seismic reinforcement method is very effective.
