Abstract

 Nankai Trough quake is predicted to occur in the near future and the disaster prevention and mitigation is becoming important. It is expected that the inter plate earthquake such as the Great East Japan Earthquake in 2011 induces severe damage caused by not only vibration, but also tsunami force from the disaster experience.<br> Hanshin expressway has been conducted various disaster prevention and mitigation studies. As one of mitigation studies, the collision analysis between the large drifting ship and the Hanshin Expressway cable stayed bridge located along the coast of Osaka bay was conducted. In this study, the collision effect on the cable stayed bridge was obtained by using the 3-D frame analysis that is a conventional method for seismic analysis and taking the collision force evaluated from the fundamental physical low into consideration. From the results of this study, it was found that the effect of impact force on the cable stayed bridge is not critical.
