• In the usual analysis of floating structures, rigid body motion is analyzed first and after that, over-all structural response is analyzed as an elastic body. For large scaled floating framed structures, however, elastic deformation of structural member may affect the motion of them. In this paper, a method analyzing the response of floating framed ocean structures subjected to periodic waves is presented, where flexibility of structural members is included in equations of motion and so internal stresses of them are calculated simultaneously with the motion. In this method, functions of members are assumed to be divided into two. One is a rigid body with mass, shape and sizes and the other is an elastic beam with elastic rigidity. By using this analytical model, equations of motion are introduced in the matrix forms. The calculations were compared with experiments by simple floating models and agreement of both was fairly good.
