Abstract
Cabinet facility is known as a high-frequency nonstructural component, and its failure is directly affected by dynamic characteristics of ground motions (i.e., frequency content, amplitude, and duration). This study aims to investigate the seismic vulnerability of a nonstructural component in the nuclear power plant (NPP) induced by the predominant frequency of the ground motions. Time history analysis is performed for eighty ground motions of low- and high-frequency motions. The results indicate that the high-frequency ground motions significantly increase the peak acceleration at the top of the cabinet. In contrast, the low-frequency content motions have less impact on structural seismic behavior.
