【 摘 要 】

Dynamic analysis of a four legged offshore truss structure under the effect of wave forces is conducted in this study. The structure is a three-storey space frame system formed of cylindrical members whose legs are supported by lateral bracings and vertical diagonals. The structure and its environment are numerically modelled by the finite elements method with the fluid-structure interaction. Due to climatic reasons, various wave theories may be applied to the structure. Therefore, the offshore environment is modelled in numerical analysis by the Linear, Stokes 2, and Stokes 5 wave theories, separately.
