Abstract

<p>As is the case with other natural phenomena such as seismic motions and tsunamis, the influence on the facilities by the permanent displacement of the ground is evaluated appropriately considering its uncertainty which is evaluated by hazard analysis. And, mitigation measures should be taken in accordance with the evaluation result. In this paper, trial analysis where fault displacement is input at the lower surface of the base slab of a PWR type reactor building is performed. In this analysis, structural safety is assessed by using nonlinear finite element models of reinforced concrete members such as the base slab of the reactor building.</p>
