Abstract
Mean annual financial losses due to seismic events in Italy are about 2–3 billion euro. For this reason, in recent years increasing attention has been placed on strategies to reduce the seismic risk of the national building stock. In this work, a comparative seismic loss analysis of an infilled R/C building is performed using the FEMA P-58 probabilistic framework and the tool PACT. The objective is to evaluate how the structural modeling and the characterization of structural and nonstructural elements fragility can affect the loss estimation. Fragility and consequence functions for discrete damage states are assumed for structural and non-structural components. A case study prototype typical of Italian pre-1970 R/C infilled buildings is chosen. Nonlinear Incremental Dynamic Analyses (IDA) are performed for three 2D modeling configurations. Financial losses are expressed as median values of repair costs at different hazard levels or in terms of Expected Annual Loss (EAL).
