Resumen de Planning of worn- out context of residential districts using passive defense approach
Unpredictable events annually have a major contribution on the financial and life damages in the world. Today, one of the problems in preserving human and material resources and the development of countries is the occurrence of natural or unnatural disasters that the lack of proper management to control and counteract them will increase the area and extent of damages caused by crises. On the other hand, urban worn-out context is also considered particularly in planning and urban management interventions due to the type and degree of worn out and the possibility of high degradability. The district of western division in Tehran as one of the worn-out context of the city has improper conditions such as lack of facilities, lack of public users, unsuitable passages and the high percentage of residential buildings and requires planning to improve the conditions of a district. Planning of these context with passive defense approach provides the possibility to minimize the reduction and elimination of many problems by considering the principles of passive defense to prevent the injuries when occurring threats while improving conditions. This research is to plan for the worn out context of Tehran's western division district with passive defense approach conducted using the descriptive-analytical method. The results of this study show that by cases as retrofitting buildings in the worn out area and proper distribution of the users and the transfer of vulnerable users from the area as well as improving the worn out districts can affect its vulnerability against the crisis.
