Derivation of Hybrid Vulnerability Functions Based on Observational Data for Iran

Abstract eng:
Iran is located on one of the most seismic areas of the world. It is situated over the Himalayan-Alpied seismic belt and is one of those countries which have lost many human lives due to the occurrence of earthquakes. Therefore research studies related to seismic risk assessment is very important in this country. Based on this study, a data bank of post-earthquake damage distributions observed in the earthquake events; and judgmental vulnerability relationship developed for Iran, a hybrid methodology of vulnerability analysis is applied, involving elements from both empirical and judgmental methods to derive new hybrid fragility curves for different building types. Hybrid curves show more better correlation between data in comparison with empirical curves had been derived.
