概要
A simplified evaluation method for the nuclear power plant structures subjected to impulsive forces caused by the floating debris and tornado missiles is proposed. In this study, the maximum shock response displacement is obtained on the assumption that the impulse of the collision is constant. Then the maximum shock response displacement is used to evaluate structural damage by the classical elastic analysis. To verify the proposed method, impact analysis with FEM was performed. Comparisons of the maximum effective strain between the impact analysis and the proposed method show the conservative estimation of the displacement and the strain by the proposed method.
