Abstract

In order to reduce the vulnerability of Tehran, before any planning and decision-making, it is necessary that the earthquake damages based on its different conditions and Status shall be analyzed before its occurrence to obtain a clear vision of probable earth quake happening and its resulting consequences and on the basis of simulating probable earth quake in different intensities, the vulnerability maps is prepared. The current study tries to design earth quake scenarios with different intensities by Fuzzy AHP model and GIS software to present  a proper estimation of vulnerability of Tehran municipality district No.3 against earthquake.
This study is of applicable type and descriptive – analytical. Applied data is of documentary and field type.
 The results of the study  indicate that  the amount of  incurred damages  to the buildings of district No.3 are are divided into five levels of “very low, low, medium, high and complete  destruction; in designed scenarios of  is Scenarios designed 6 Mrkaly 53/88,26/77,19/04,0/04,0/25;  respectively in 7 Mrkaly 23/28, 21/22, 9/31, 26/42, 19/75; 8 Mrkaly 0/54, 59/33, 20/22, 9/55, 46/97, respectively.
 The highest level of vulnerability Based on the number of damaged buildings  are at municipality  districts of 2, 3, 5, 4, 1 and 6 respectively which  is due to the use of undurable and weak materials  construction works, existence of  worn textures and high  age of the existing structures, structures located on qanats , the population centralization in old  and high density textures and  tower construction  without performing  studies regarding comprehensive plans, and  also  lack of following the  common standards in the country including by law 2800.
