TSUNAMI-BRIDGE INTERACTION OF KESEN BRIDGE BASED ON DAMAGE MECHNISM OF BEARING SUPPORTS AND VISCOUS DAMPERS

Abstract

 Video movies of the tsunami and the numerical simulation have been evidences to evaluate the tsunami-induced force to the bridges in previous researches. However, it is still difficult to identify the bridge behavior up to the stage of wash-out of superstructure. This paper focuses on the damage traces observed at the bearing supports and viscous dampers equipped in Kesen Bridge, so that the behavior of Kesen Bridge subjected to the tsunami-induced force is clarified precisely based on facts of those damage traces.
