Urban vulnerability is the quality and extent up to which the components and elements of a city are damaged in the event of an incident. The study of a city’s structures and the zoning of its vulnerability from the perspective of passive defense is a step towards the future prospects of a safe city. This paper studies the vulnerability challenge in city structures from a passive defense point of view and it is the expected modeling approach to identify these infrastructures. The statistical society of this paper is Dezful city, Khouzestan province; as the center of war provisions. This is a practical study from an objective point of view and an analytical descriptive study methodologically. It is based on space-modeling studies approach with10 formats of characteristics being identified and with the assistance of mixed analysis of AHPFUZZY-GIS, weighing distance maps has been designed and standardized. OVERAL FUZZY tools in ArcGIS application are used for spatial distribution and studying defense vulnerability. The results indicate that in analyzing indexes, police stations and warehouse indexes were the most significant ones in passive defense with weighs of 0.116 and 0.113. In Dezful's microsphere of urban structures, the following places were in danger of air strike attacks and had a completely vulnerable situation: 28/41 warehouse centers, 29/84 residents, 38/62 shopping centers, 32/35 business offices, 100 terminals and restrooms, 27/18 religious centers, 28/39 education centers and 38/33 the roads. According to these results it is clear that the situation of Dezful city from passive defense view is precisely not suitable for the times of air strikes and in case of any attacks the city will face major problems.

Iran is located in one of the most sensitive parts of the world; a place where besides wars and terrorist attacks, embodies many natural disasters every year and brings a lot of human and financial damages. So, because of the accumulation of material and spiritual capital of the country, focusing on cities is very important. Cities of Khouzestan Province, in addition to a lot of damage during the eight years Iraq war against Iran, nowadays are also exposed to different types of natural and manmade disasters. Dezful has a strategic situation in the province and according to the records during the holy defrence war, it had repeatedly been attacked by enemy missiles. Hospitals are one of the most important infrastructures of cities that, in addition to providing services at normal times, should also perform well during the crisis. Obviously, the hospital that has properly implemented the principles of passive defense can play such a role. Accordingly, Dr. Gonjavian Hospital in Dezful has been selected as an active and important hospital in Dezful whose design and location have been investigated. According to criteria extracted for the analysis, the hospital in terms of location is consistent with the principles of passive defense. But in terms of architecture and building design, defense principles have been partially implemented at the building and other principles and different designs can be performed in hospitals’ vision without making major changes to the building.

Due to the particular importance of hospitals and health centers structures and with an eye toward their level of performance in the time of natural disasters and wars, the analysis of vulnerability of hospitals and health centers structures gains significant importance. The aim of the present study is to analyze the vulnerability of hospitals structures from the perspective of passive defense. The main data of this survey which encompasses information regarding studies cases of health centers and hospitals were gained via the field studies in the form of observation, interview, and questionnaire. For the analysis of the information and data, the softwares of Expert Choice, Excel, and ArcGIS were used. The employed model, namely that of Fuzzy Analytic Hierarchy was used through inquiry of five experts (five faculty members of the civil engineering department of Jondishapour University of Dezful). In the present survey, three hospitals (Ganjavian, Ayatollah Nabavi,and Afshar) were analyzed as studied cases. The findings of the research demonstrated that Afshar hospital with the rate of 2/069158 has the highest level of structural vulnerability among the hospitals of Dezful. Ayatollah Nabavi hospital with the vulnerability of 1/834399 that comes next. Ganjavian hospital with the figure of 1/426003 has the lowest rate of structural vulnerability among these hospitals of Dezful.

The particular position and special characteristics of Iranian geography toward great powers since a long time ago, have led Iranian governments to consider the importance of creating military and defensive positions. Dezful texture has been created during Sasani dynasty and has survived until now. This study tries to investigate the way of using passive defense in historical cities of Iran, including Dezful.the study has used historical and descriptive-analytical method; acquiring historical information and documents through documentary and librarian methods. The results show that that choosing the location of historical cities of Iran including old texture of Dezful has been carried outin a way that by relying on surrounding facilities and the least costs kept the city away of enemie's access. This job was done in a way that natural possibilities were used and also it was according to human-made components of passive defense likemoats and forts.
