Abstract

Nuclear power plant structures amy be exposed to aggressive environmental effects that may cause their strength and stiffness to decrease over their service lives. Although the physics of these damage mechanisms are reasonably well understood and quantitative evaluation of their effects on time-dependent structural behavior is possible in some instances, such evaluations are generally very difficult and remain novel. The final goal of this study is to develop the reliability analysis of RC containment structures. The cause of the degrading is first clarified and the reliability assessment has been conducted. By introducing stochastic analysis based on random vibration theory, the reliability analysis which can determine the failure probabilities has been established.
