Explanation of physical-social resilience of historical worn-out fabric with emphasis on sustainable urban form

Urban fabrics today face a number of structural problems that have a lot of impact on the extent of damages. Urban form as comprehensive idea, composed of all visible elements of the urban center, whether natural or artifact, and the spatial crystallization and form of the activities of the urban community, which is exemplified by its three-dimensional nature, in addition to the surface, in bulk. This composition includes human artifacts, buildings, road networks, open spaces and urban facilities, and natural elements such as topographical complications, currents and vegetation, and the study of its resilience can be a shortcut to measure the stability of the system on an intermediate scale. The aim of this study is to explain the structure and optimal model of the resilience in the urban form of the worn-out neighborhood. In explaining the urban regeneration approach. Finally, with the formulation, explanation and emphasis on the fundamental concepts of sustainability, which is one of the most respected developers in developing countries, our country can, given the ancient history of historical cities in most of the metropolis of the country, and changing the nature of the type of intervention in Development of tourism as well as optimization of tissue efficiency and these issues are considered as a principle in most urban design projects. To suggest researchers in the future research, we can examine the more accurate relationship and the quality of the relationship between burnout and inefficiency in neighborhoods, which expresses and analyzes the type of this intersection as a systemic relationship.
