Abstract :

Cities today extend their spatial territories, whereas they become more susceptible to natural and man-made threats. Being located in the earthquake-prone belt of Himalayas, on average every five years, Iran faces an earthquake of magnitude of seven in Richter scale. Given the existence of active faults, Tehran is always at risk of earthquakes and has higher probability of accidents due to socio-economic-physical risk factors like high concentration of population, weak structures, weak adaptation of public services, housing, and so on, compared to other cities in Iran. As is clear, cities are complex systems constantly exposed to various interactions. Thus, to make such a great complex with its own complexities resilient and efficient, we need to draft some principles that clarify the path to achieving this goal. The purpose of the present study was to examine the components of urban resilience (case study: District 16 Tehran) with an emphasis on the natural incident earthquake. The study was conducted using a questionnaire, determining the total volume of samples, and using Cochran method along simple random sampling formula. Thus, 200 questionnaires were analyzed according to a 5-option Likert scale and t-test using SPSS. The results showed that urban resilience components at economic level include the role of providing services and increasing incentives for housing reform with an average of 3.39 percent was the most proper and the belief in planning to reduce the devastating effects of the earthquake with the priority of increasing revenue of people with an average of 1.92 are the most improper economic components.  The social level includes the participation in training courses to deal with the damage caused by an earthquake and to reduce its effect with an average of 3.38 as the most proper and transfer the experiences for reduction of the impact of earthquake with an average of 1.73% is the most improper components at social level. . Moreover, at the physical-environmental level studied, the increase in the damage caused by the lack of a prior warning system and evacuation systems with an average of 3.64 were considered the most appropriate and the trust in housing due to consulting with domestic architects and consulting engineers with an average of 2.016 was the most inappropriate case at physical-environmental level.
