Measuring Physical Dimensions of Urban Resilience in The Face of the Natural Disasters (Earthquake) (Case Study: Tehran's 12th District)

The damage and casualties caused by natural disasters will depend on the state of readiness of the event. Building resilient cities of various sizes is a suitable and effective way to strengthen the structure of the city to deal with crises and natural and unnatural disasters. This study in terms of purpose is applied and in terms of method is descriptive - analytical. In this study, data collection was based on library and documentary methods and for data analysis we used AHP Fuzzy model. Results showed that the measure of physical properties of texture with a weight of 0.424, and sub-criteria’s such as Street width with a weight of 0.238, building resistance with a weight of 0.120, access to the park with a weight of 0.102 are the most important criteria and sub-criteria in physical resilience of Tehran's 12th district. The final maps of regional physical resilience showed that only 1.03 percent of the area texture has high resiliency and 74.64% of the area has medium resilience and 24.33% of the area has low resilience. Also, the results showed that Tehran's 12th district buildings according to the age of buildings and their quality, the narrow access, the fine-grained segmentation, the increased occupancy levels, and the lack of open space that threaten the peoples’ lives in this area are in contrast with urban resilience. This issue warns us of more damage and casualties when an earthquake occurs.
