Abstract
This paper presents a three-dimensional numerical analysis for wave response of large floating structures using finite element method. Up to now, wave response analyses using finite element method had not been studied because this method required a large computer memory and had to deal with the infinite boundary condition. At the present time, progress in computer is remarkable, so it is possible to perform such an analysis by finite element method using the infinite element. The aim of this study is to develop a method for wave response analysis of large floating structures by finite element method. The model stricture has a length of 1000m, a width of 500m, and a height of 4m. Finally, Effects of important parameters such as the direction of incident waves, the incident wave length and plate rigidity on the response of the structure are discussed.
