Abstract

More than 70 girders were washed away by the Off-Sumatra Earthquake and ensuring Tsunami. Numerical Analysis using DEM was performed to investigate the failure mechanism. The result showed, as flow velocity of Tsunami increased, the acting force to the girder and total movement of girder increased. Whether the movement of girder occurred or not is controlled by the coefficient of friction between the girder and beam, and the flow velocity of Tsunami.
