Expressions for response to ground motions included hydrodynamic interaction are presented by using finite element method both for structure and water. Numerical results are shown for uniform cylindrical tower and cylindrical tower with a circular disk. The effect of surrounding water shifts its natural frequency and damping constant lower. These results are compared with the experimental results., 長崎大学工学部研究報告, 16(27), pp.143-150; 1986}, pages = {143--150}, title = {固定式海洋構造物の耐震性に関する基礎的研究(第1報:理論解析)}, volume = {16}, year = {1986} }
