Abstract

Great tsunamis passing through structures in some cases cause structural damage by the hydrodynamic force. Although there are many empirical methods to estimate hydrodynamic force which are expressed with a function of flow depth, flow velocity or Froude number, the predicted hydrodynamic forces exhibit considerable scatter. In order to investigate the characteristics of the hydrodynamic force acting on the front face of a structure and propose the prediction method of the hydrodynamic force induced by a tsunami, we have carried out three dimensional numerical simulations of tsunami passing a structure.
