Vulnerability City buildings against natural disasters (Earthquakes) (Case Study: Mohtasham Neighbourhood Kashan)

Correct understanding Dimensions and principles Crisis Management From earthquake in urban areas can as the first step in the process Crisis Management and as one of the most basic instructions direction Implementation of Crisis Management earthquake is considered. In order normative planning to reduce the vulnerability of urban buildings and to present a clear picture of possible occurrence of earthquake and its consequences, assessment of urban vulnerable zones is essential. The aim and methodology of this research are applied and descriptive-analytical, respectively. In order to vulnerability evaluation of worn out tissues of Mohtasham district of Kashan city, from the perspective of disaster management, the AHP model and for weighting of indices, Expert choice software, were used. To assess of the vulnerability, 9 indices were used. The extent of damages to buildings of this district of city has been divided in five groups: very low vulnerable, low, medium, high and complete destruction. The results showed that, in terms of vulnerability, 10 percent of district in very low, 19 percent in low, 15 percent in medium, 47 percent in high and 9 percent are located in very high vulnerability.Spatial distribution of vulnerability in the center of district is more than the other places due to non-use of resistant materials, undesirable quality and high antiquity of buildings. According to relevant results. Due to physical problems of Mohtasham, earthquake crisis management approach is as an effective solution in order to preserve the tissue and reduce damages to the tissue because of earthquake.
