The method of hydro-elasticity considering the fluid and structure interaction could calculate structural safety of floating structures effectively based on the rigid characteristics of very large floating structures(VLFS), which is used here to analyze the global wave loading and structural stress responses of single module of VLFS. In this paper, the natural mode and shape of vibration and intrinsic frequency are calculated by 3D FEM for single module. Then the harmonic frequency and principal coordinate responses of single module are obtained by mode superposition method and BEM method. Forwards, the structural stress responses of each mode and global stress responses are investigated; meanwhile the dangerous loading cases and the structural strength of single module are assessed. The results provide a certain guiding meanings for structural optimized design and safety assessment of VLFS.
