In order to perform the reliable design of offshore structure, it is important to clarify the dynamic response characteristics due to severe dynamic forces. In the present study, the dynamic responses due to wave and seismic force which have different dynamic properties are examined. It is shown that the reliable evaluation can be carried out by clarifying effects which are caused by the nonlinear dynamic response and dynamic characteristics of external forces.
