Given that cities have the majority of the country's population and are often the economic, political, cultural, social and governance centers in countries, theirreadiness against crises (passive defense) should always be considered by the relevant experts. Organizing the city on the scale of the neighborhood (as the smallest and most effective urban unit) based on the requirements of passive defense, in order to deal with the crises (natural and man-made) and minimizing the hazards using geographical techniques and urban planning, are the objectives of this research. Therefore, the sixth district’s neighborhoods of Tehran’s 2nd region were selected as a case study and the results of the research were presented so that the possibility of generalization of similar surveys and studies in other urban areas would be provided. The present research is an applied- type, and the method of the research is normative-analytical. The scientific foundations of this research are based on the concepts of urban crisis management with an emphasis on geography and urban planning knowledge. In this research, after the recognition and evaluation of the present situation, the dimensions of the vulnerability of neighborhoods at the time of the crisis, the strengths and weaknesses, as well as the threats and opportunities of each neighborhood have been investigated with the passive defense approach, and the relevant conclusions have been drawn on this basis. Data collection was done based on library method and field studies, and a comparative method was used to provide the conclusions. In this research, the SWOT analytical technique was used to determine the strengths and weaknesses, threats and opportunities, as well as to provide strategies, policies and suggestions for necessary actions, and ArcGis software was used to display and analyze the descriptive data. The results of the research indicate that the attention to components such as city structure, urban texture, city form, urban land use, and finally the social contributions of residents of each neighborhood, can make it possible to organize urban neighborhoods based on the requirements of passive defense. The results of the research reflect the fact that paying attention to the components such as city structure, city texture, city form, urban land use, and finally the social contributions of the residents of each neighborhood, can make it possible to organize urban neighborhoods based on the requirements of passive defense.

Worn-out structures confront structural, social and economic challenges. The three indices of transience, impermeability and granulites are major features of such structures. "Martyre Dastgheib" area as one of the worn-out structures of district 9 in Tehran is facing various structural, social and economic challenges. The aim of this study is explaining distribution of failures and their interrelationships, and the comparative study of mentioned indices in order to achieve sustainable urban neighborhood. It seems that the best solution for controlling and reducing worn-out urban structures is spatial analysis from structural, economic and sociocultural aspects. Current study was done aiming at organizing "Martyre Dastgheib" area with a systematic perspective whose main bases are described through the improvement of physical appearance and urban revival. To this end, the major question is whether structural, social and economic indices influence on vulnerability analysis of worn-out structure of "Martyre Dastgheib" area identically.
The research type is descriptive- analytical and survey. Data were collected through library-based procedures and field study. In analysis step, firstly, values and data for all indices were extracted, and then respective indices were weighted according to Analytical Hierarchy Process (AHP). Findings show that by integration of structural, economic and social layers for measuring vulnerability of worn-out structures, they are classified into low-vulnerability to high-vulnerability areas. 24.3 percent of the area was with high-vulnerability, 47.3 percent faced to considerable vulnerability, 14.7 and 13.7 percent faced to average and low vulnerability, respectively. Considering this finding, organization of worn-out structure in this area through an integrated approach including improvement, modernization and reconstruction is possible.
