A method for dynamic response analysis of an offshore cylindrical shell structure including soil and fluid interactions to horizontal earthquake ground motion is presented. The system considered is a thin elastic circular cylindrical shell which is partially or totally submerged in water and connected at its base to a rigid circular disc footing of negligible thickness attached to the surface of a perfectly elastic halfspace. The hydrodynamic pressures acting on a shell surface can be analytically obtained on the basis of a linear potential flow theory. Horizontal translation and rocking motions are assumed for the footing on an elastic halfspace and the interaction forces between the footing and the halfspace are approximated by semi-empirical expressions. The steady state response is determined over the range of interest of excitation frequency and the effects of various structural, soil and fluid parameters on structural response are discussed. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
