Accidental collisions occur frequently between bridge superstructures and over-height vehicles passing under the bridges. In order to keep the damaged bridge in a serviceable state, it is important to conduct quantitative evaluation of its damage level and residual performance. In this study, we performed FE simulation of an actual collision accident between PC girder and container truck, and confirmed that the simulation reproduced the condition of damage from the actual incident such as cracks and deformation. In addition, we conducted the collision analyses assuming various collision cases and also static vertical loading analyses of PC girder received collision. The analyses elucidate the effect of collision speed, collision angle, gross vehicle weight on the damage of PC girder. Based on results of each analysis, the correlation of damage and residual performance is assessed.
