Analysis of the Worn-Out Tissues Characteristics and Providing of Intervention Pattern, Case Study: Eslamshahr City, Tehran

Abstract

This paper aims to prioritize intervention in urban deteriorated fabrics of Eslamshahr city. Worn-out textures in Eslamshahr (south west neighbor of Tehran), despite having potential facilities, unfortunately, in areas such as network infrastructure, water, electricity, telephone, and gas networks are becoming physical problems of the city against unforeseen events such as an earthquake. So that improvement, renovation and restoration of these textures could be very effective in making the Eslamshahr development sustainable. The studied deteriorated fabric covers an area of 104 hectares and has a population of about 42,664 people. Problems and challenges such as the domain of low-income people living, non-proportional distribution of services, marginalization and extensive urban deteriorated are among the most evident challenges. In this study, using the analytic hierarchy process (AHP), the weighting and ranking of triple structures and variables related to each structure of the worn-out texture in Eslamshahr region took place. Weighting of criteria has been carried out based on research and comment of professionals and experts. Intervention indicators in the studied fabric are recognized and prioritized based on physical, social and economic factors. Considered indicators include type of Land Use, Passage network, Building occupies, Building Density, Number of floors, Building Life, Number of blocks, Constructions materials and skeleton, Separation of parts and Building quality. After evaluation using analytical hierarchy process and according to opinions of experts, rank each of the parameters was obtained and then with using ArcGIS software overlay map have been designed and evaluated. Result of this study revealed which a pattern can be presented for intervention of worn-out texture in Eslamshahr.
