Seismic Fragility Analysis of a Nuclear Primary Containment Structure

Abstract

Abstract. A seismic fragility curve is an important tool in the probabilistic

Method for evaluation of concrete containment structure subjected to earthquake excitation and internal pressure increase

“…Several studies have been carried out to understand the ultimate seismic response and seismic risk of the NPP structures subjected to beyond level ground excitations. [9][10][11] Most studies used 3D shell element to represent the containment structures. By using the layered formulation, the nonlinear properties of material were considered in the in-plane direction only while the out-of-plane shear deformation was assumed to be linear.…”
