There are few research about overlapping phenomenon of earthquakes and tsunamis. As a progress report, this study aims to calculate the behavior of a structure and fluid when an earthquake acts by applying the fluid-rigid-body interaction analysis method.
The results confirmed the following: (1) the force acting on the breakwater calculated by this analysis method is approximately the same as the design value. (2) dynamic water pressure becomes slightly smaller when the structure moves. (3) it is possible to evaluate the structural stability during an earthquake. (4) compared with FEM analysis (program code: FLIP ROSE), although there are some differences in the results of displacement due to the influence of the parapet, but it is confirmed that the similar earthquake response analysis regardless of the analysis method and time.
