Verification on Collapse Process of Aso Bridge during the 2016 Kumamoto Earthquake by ASI-Gauss Method



The 2016 Kumamoto Earthquake caused serious damages not only for private houses but also for infrastructures in Kumamoto prefecture. For example, a huge landslide happened after the earthquake and Aso Bridge, which was constructed in the same location of the landslide, totally collapsed. Since there is no observation data, it is difficult to get consensus on the main reason of Aso Bridge’s collapse. On the other hand, it is important in earthquake-resistant designing of bridges to investigate critical factors and failure processes. Therefore, in this paper, a numerical analysis of the Aso Bridge failure is conducted by ASI-Gauss method in order to verify the collapse process.
