摘要：

A simplified method of the seismic response analysis using the hydrodynamic restoring force coefficients for an arbitrary shaped three dimensional offshore structure with multiple degrees of freedom has been developed. The present method was verified through the comparisons with the more rigorous numerical solution using Green's function. The frequency characteristics of the hydrodynamic restoring force coefficients were investigated. The response of twin cylindrical structures were analyzed, and the structure interaction effects due to the fluid compressibility were discussed.
