Floor Response Evaluation for Building Subjected to Liquid Filled Missile Impact

In case of infrastructures such as nuclear power plant subjected to unexpected external load, the interest in the safety of target structure is increased. The loss of structural function for target structure by unexpected external load and the failure of equipment inside the target structure due to vibration after impact are highly important. Thus, vibration evaluation of the structure is essential for safety of the structure.. Generally, missile-target interaction method and force-time history method are used in the impact analysis. Missile-target interaction method can obtain the numerical results more than force-time history method, because of considering stiffness, mass and shape etc. of missile. The liquid filled missile, nodal mass missile and force-time history for the missile are used in this analysis. The difference of results for three cases should be obtained using this analysis. The spread phenomenon of liquid in case of modeled liquid should be shown better than nodal mass model
