Application of AHP Method and Site Specifications in Seismic zonation and building vulnerability assessment (Case Study: Kermanshah City)
Different methods for seismic zonation and building vulnerability sassessment are produced in different parts of the world. In these studies, seismic zonation is generally based on the geotechnical profile of the soil and the shear wave velocity. In 2013, Karmania hazard model (KHM) was presented to Iran, in which seismic zonation and vulnerability assessment of buildings and individuals in the worst earthquake scenarios are based on the basic parameters of the site, such as soil texture, groundwater level, microteremore data, and alluvial depth. In this study analytic hierarchy process (AHP (is applied in KHM model for seismic zonation and building vulnerability assessment of Kermanshah city. The results show that the vulnerability level for 80% of residential buildings would be low to moderate, but 2% of buildings would suffer from complete destruction (D1), 7% with very high destruction (D2) and 11% with high destruction (D3). Finally, the model is verified with the help of the data and observations from the Sarpol Zahab earthquake, which shows that the model is in good agreement with the actual earthquake data.
