Abstract
Since slamming loads on connecting bridges of trimaran is very important for the structural design. In this paper, trimaran slamming load calculation method is studied. First added mass caused by typical hull section and wet-deck slamming are investigated, then wet-deck slamming peak pressure are gotten by modified flat slamming theory with considered of the effect of air cushion, the regression equation of which is given by statistical process. Finally, the time-spatial distribution of slamming pressure along the wet-deck is given. This method can provide a reference for the preliminary design and operation of trimaran.
