This paper presents damage survey of a plate girder bridge, namely Tawarayama Bridge which is situated on Kumamoto Prefectural road No 28, Tawarayama bypass, where the damage related to the bridge is enormous and elucidates the damage mechanism that can occur in that type of bridge due to earthquake with epicenter which is very close to bridge. At first, the parts of Tawarayama Bridge are investigated in order to find out the damages and examine the factors of occurrence. Then, seismic response analysis of Tawarayama Bridge subjected to 2016 Kumamoto earthquake motion is carried out. In observing the damages, the local buckling behavior of steel main girders are found. So shell elements are applied in finite element model to consider local buckling behavior. Frequency analysis is carried out to grasp the vibration characteristics and after that, the time history response analyses are performed using earthquake ground motion in both longitudinal and transverse directions to investigate the dynamic response of the bridge. The predicted earthquake motion simulated by Professor Yoshiya Hata from Osaka University is applied for dynamic response analysis. Finally, the results for comparison of numerical results with real disasters are discussed.
