An engine nacelle was possibly supposed to drop on a large floating structure 'Mega-Float', which is planned to be a marine airport. The structure is mainly constructed with steel and paved with concrete slabs. The damage of the floating structure with and without concrete pavement was investigated by numerical simulation. A non-linear finite element analysis program with explicit integration, LS-DYNA3D, was utilized to calculate the behavior of concrete fracturing. By simulation, the colliding phenomena, absorbed energy on the deck, and engine nacelle penetration were calculated. By parametric calculations, it was found that the concrete pavement was effective to increase impact energy absorption against an engine nacelle collision and the concrete pavement should be considered in structural design.
