Abstract

This paper introduces a simplified methodology to develop state-dependent fragility relationships, based on nonlinear static analyses combined with the Cloud Capacity Spectrum Method. Capacity reduction factors for structural members are applied to simulate the attainment of a specific damage state under a mainshock. A cloud-based procedure is adopted to compute fragility analyses. The procedure is illustrated for a case-study building designed for gravity loads only. Results highlight the importance of considering the effect of cumulative damage in the fragility analysis of buildings. The proposed methodology may be used for seismic-risk assessment studies accounting for ground-motion sequences.
