Abstract

<p>The 2016 Kumamoto Earthquakes caused serious damages not only for private houses but also for infrastructures in Kumamoto prefecture. Many bridges were damaged by the seismic waves. In this study, we focused on the Aso Bridge which collapsed immediately after the main shock. A huge landslide happened after the earthquake and Aso Bridge, which was constructed in the same location of the landslide, totally collapsed. It is difficult to get consensus on the main reason of Aso Bridges collapse, since there is no observation date. On the other hands, it is important in earthquake-resistant designing of bridges to investigate critical factors and failure processes. In this paper, a numerical analysis of the Aso Bridge failure is conducted by ASI-Gauss method, which is a branch of finite element method, in order to investigate the collapse process.</p>
