Probabilistic Seismic Safety Assessment of PSC Containment Building Considering Nonlinear Material Properties

재료비선형 특성을 고려한 PSC 격납건물의 확률론적 내진안전성 평가

The seismic safety of the prestressed concrete containment building was evaluated by the seismic fragility analysis based on the nonlinear dynamic time-history analyses. Four kinds of earthquake ground motions were used for the seismic fragility analysis of the containment building to consider the potential earthquake hazard. The conventional seismic fragility analysis of the safety related structures in nuclear pouter plant have been performed by using the linear elastic analysis results for the seismic design. In this study, the displacement based seismic fragility analysis method was proposed.
