Rapid assessment of the damaged buildings in a disastrous event is a drastic measure to be taken in order to allocate shelter to unsheltered people as quick as possible. Natural disaster as earthquake may cause considerable losses to the cities and prevent development processes. Urban planning as well as city designing projects aims to decrease vulnerability of buildings against earthquake. In this direction, the first step is to recognize and analyze the rate of damages exerted to every urban element using proper models. Spatial data along with attributes of building elements and their behaviors against earthquake shocks has been employed using Analytical Hierarchy Process (AHP) to evaluate the vulnerability of the city against earthquake shocks. Also the weight of every criterion in building destruction has been determined through this method using GIS analysis. The results of this paper show that historic fabric of the city of Kashan is very high Vulnerability due to exhaustion and the use of less durable materials in construction and old buildings.
