The 2016 Kumamoto earthquake caused extensive damage to road bridges in mountainous areas, it needs to be restored quickly and temporarily, and it is necessary to take measures to prevent the main structure from sustaining serious damage. In this study, it proposes a structure that absorbs energy when the abutment moved and pushed the main girder. It is set at the tip end of main girder. In this paper, the method is to avoid damage to the main structure by causing partial damage at girder ends. The method was to reduce the stiffness in a certain location to cause local buckling, and a nonlinear analysis was performed using the stiffness reduction as a parameter. The results of an analysis to confirm the effectiveness of the method are shown.
