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.
