Abstract

When a super large floating structure, constructed with the steel and concrete slabs, is used as airport, there is a slight possibility for airplane and engine to drop on it. For designing the super large floating structure, it is important to verify the safety of it against the airplane collision. In order to clarify the behavior of deck structure and concrete pavement during collision, numerical calculations are performed utilizing non-linear dynamic FEM program 'LS-DYNA-3D'. The minimum thickness of 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. And also, it is shown that the concrete pavement is effective to absorb the dynamic energy produced by an airplane collision. As the above 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 at airplane collision is developed to save the computing time.
