The key components' explanation of increasing Tehran physical resilience against earthquakes with a structural analysis approach (Case study: District 10)

The present study is a field research with a descriptive-analytical approach and seeks to answer the basic question: What are the key components of increasing physical resilience in the 10th district of Tehran in the future according to the current situation? In this research, in order to codify a theoretical framework at first, the subject is described in detail using the documentary method, literature and theoretical foundations, and then by relying on the environmental scanning technique and the Delphi method, the experimental data is extracted. The statistical population includes 20 urban experts and specialists. Also, the sampling method used is a purposive sampling. In the first step of the research, based on the review of theoretical texts and documents about resilience and dysfunctional urban texture with emphasis on the physical dimension, 41 variables were extracted and then in the next step, experts' opinions regarding the outcomes of these variables on each other through distribution of 20 Questionnaires were collected and finally the answers were analyzed using structural interaction analysis method in MICMAC software. In this analysis, the extent of direct and indirect effects of variables on each other and on the future trend of physical resilience in the district 10 of Tehran against earthquake was determined and then the key explanatory factors of the research topic were extracted. In the other words, out of a total of 41 influential initial variables, 11 variables were chosen as the key factors affecting the future trend of physical resilience in the district 10 of Tehran in the face of earthquakes. The aftermath of this study represents that the relationships of key components are so effectual and impressionable.
