This study investigated the tsunami force acting on onshore structures using a numerical program, three-dimensional one-field model for immiscible multi-phase flows, which is based on Navier-Stokes solver. In this paper, the characteristics of tsunami of oil storage tank and house structures studied to the distance between the seawall and structure. In addition, the study compared and analyzed the tsunami forces determined by considering drag force only and considering both drag and inertia forces. These numerical results were compared with the design standard. As a results, the case of considering the both forces is more close to numerical result than that of considering the drag force only.
