主 题：seismic risk reliability analysis infrastructure components loss estimation uncertainty
摘 要：This paper proposes a risk analysis framework for substation structures based on reliability *** though several risk assessment approaches have been developed for buildings,detailed risk analysis procedures for infrastructure components have been lacking in prior *** proposed framework is showcased by its application to a system of interconnected structures at a power substation in *** element models of structures are developed and validated in accordance with previous *** uncertainties in the material,mass,and geometric properties of structures are described by random variables that are input to the finite element *** artificial ground motion model is employed to comprehensively consider uncertainty in ground *** Carlo sampling is subsequently conducted on the library of probabilistic *** analysis resulted in the loss distribution in the life cycle of ***,the loss associated with six earthquake scenarios having specific magnitudes and return periods is *** application provides insight into the most vulnerable equipment in the considered ***,introduced risk measures can guide stakeholders to make risk-based decisions to optimize design or prioritize a retrofit of infrastructure components under conditions of uncertainty.
