When a super large floating structure, constructed with steel and concrete slabs, is used as an airport, there is a slight possibility for an airplane and engine to drop on it. For designing the super large floating structure, it is important to verify its safety against an airplane collision. In order to clarify the behavior of the deck structure and concrete pavement during collision, numerical calculations are performed utilizing a nonlinear dynamic FEM program. The minimum thickness of the deck plate and concrete pavement, which are necessary to prevent the penetration of the airplane or engine into the deck plate, are shown based on the results of calculation. It is also shown that the concrete pavement is effective to absorb the dynamic energy produced by an airplane collision. As this numerical calculation requires an enormous computing time, it is not economical to apply this at the preliminary structural design stage. So, a simplified model for simulation of the phenomena during an airplane collision is developed to save the computing time.
