An airplane or its engine was possibly supposed to drop on a large floating structure, 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 dynamic finite element analysis program with explcit integration, LS-DYNA3D, was utilized tocal culate the behavior of concrete fracturing. By simulation, the colliding phenomena, absorbed energy on the deck, and engine penetration were calculated. By parametric calculations, it was found that the concrete pavement was effective to increase impact energy absorption against an engine collision and the assumed construction of deck was strong enough against airplane collision. A simplified model for parametric calculation was introduced.
