Study on prediction method of sea-shock response of floating structure considering the characteristics of propagation of earthquake waves in water and seabed (First Report)

The purposes of present study are to develop the powerful numerical method for sea shock phenomenon and to clarify the characteristics of sea shock responses on very large floating structure.The present numerical method has been considered the characteristics of propagation earthquake waves in water and seabed. Numerical computations have been carried out very large floating structures in the cases of several seabed conditions.From the comparisons of computational results, it is that the numerical results by present method are greatly different of the results with the rigid seabed condition.
