Damage and Loss Assessment of Pre-70 RC Frame Buildings with FEMA P-58: A Case Study

摘要

Past earthquakes have shown that seismic events may incur large economic losses in buildings. FEMA P-58 provides engineers, a practical tool for the performance seismic assessment of buildings. In this study, FEMA P-58 is applied to a typical Italian pre-1970 reinforced concrete frame building, characterized by plain rebars as steel reinforcement and masonry infills and partitions. Given that suitable tools for these buildings are missing in FEMA P-58, specific fragility curves and loss functions are first developed. Next, building performance is evaluated following a time-based assessment approach. Finally, the expected annual loss of the selected building is derived and compared with results from past PEER-PBEE applications to old RC frame buildings representative of the US building stock.
