Probabilistic Seismic Damage Analysis of Buildings Using Damage Scenarios
Abstract eng: In this paper the seismic damage analysis of a building at the system level, subsystem level, and component level is organized into a damage scenario tree. Damage scenarios involving building collapse, building demolition and reconstruction, and component damage are defined. Damage scenario tree analysis provides a rigorous framework for calculating the fragilities for various damage scenarios. Probabilities of different damage scenarios are evaluated for treating earthquake ground motion variability. Engineering demand parameter (EDP)-based and hazard intensity measure (IM)-based methods are used for quantifying the probability of damage scenarios. Variability in structural response due to variation of ground motion records are included on a record-by-record basis. Applications to a 9-story special concentrically braced frame office building are shown. Damage scenario fragilities are developed using damage scenario tree analysis procedure. .Keywords: damage scenario; collapse; demolition; probabilistic damage analysis
