In order to verify the validity of fault displacement fragility evaluation, behavior and damage situation of ground and structure due to fault displacement was numerically analyzed based on the damage data of the structure in the past earthquake. From these results, we examined important parameters (uncertainty factors of response and strength : median, distribution, upper-lower limit range, etc.) of fragility in fault displacement PRA of nuclear facility and their evaluation method. In this report, we show the overall outline.
