Abstract

This paper investigates the natural modes and static reponses of modularized floating structure. As an example structure, a floating parking place$(120m{\times}60m)$ is considered. In the evaluation of natural modes and static responses, numerical equations are formulated by FEM(Finite Element Method) and the natural modes are solved by subspace iteration method. By comparing responses of structures of various sizes of module unit, the effect of unit size is also investigated.
