The objective of present paper is to examine the characteristics of sea-shock responses of floating structures by using practical method (so call impedance method) considering the effect of seabed. In the present paper, the impedance method, which was considered the reflection characteristics of earthquake wave by using impedance ratio, was formulated and the characteristics of hydrodynamic forces by present method wfas compared with the results by the method of elastic sea ground and wave tank experiments and evaluation method of optimum impedance ratio was discussed. Furthermore, the characteristics for sea-shock response of floating structure wrere calculated by the impedance method with optimum impedance ratio and also these numerical results were discussed.
