文摘

Seismic vulnerability of Power Substation Equipment is studied. 3D finite element modeling & THA for a Circuit Breaker are performed. Seismic multivariate fragility functions for Circuit Breaker are proposed. Fragility surfaces provide more reliable seismic risk evaluation. Failure probability is susceptible to various PGV levels.
