Abstract the particular structure for small waterplane area twin hull(SWATH), considering the timevarying characteristics and nonuniformity distribution of slamming load, formula of slamming load varied with space and time was deduced based on the theory of plat slamming. The directly loading technology that can realtime simulate waves was applied. Then an analysis of structure vibration response characteristics of SWATH subjected to wave loads and slamming loads was conducted, and the discussion of the slamming effect on hull strength was performed. The results show that there are some particular response models under combined loads. The effect induced by combined loads actions is not twonodal vibration like monohull, but transverse bending vibration of cross structure. Combined loads actions threaten the strength of wetdeck and stanchion severely. Slamming contributes to the structure vibration response significantly and influences the overall strength and deformation.
