Evaluation and Improvement of Urban Worn against Earthquakes (Case Study Neighborhood of Shiraz Zvalanvar)

Natural disasters as the part of human life process are increasingly considerably and considered as a factor which harms humans and poses a major challenge toward achieving a sustainable development of human societies; however, some of the developed countries associated with progressions in the field of sciences and knowledge could not provide the appropriate control for preventing these natural disasters. Among these disasters, the destructive role of earthquake is so important in the human life as well the occurrence of an earthquake in a part of the world threatens the lives of thousands of people, damages most human-made installations and buildings and results into the physical damages as well as the financial ones. So the first step in dealing with this destructive phenomenon is to have knowledge about its causes and then suggest the options in order to deal with [overcome] for reducing the financial and physicals losses.Shiraz as a metropolis in Iran had an increasing or a considerable growth during the recent decades which resulted into the non-standard buildings as most of them were the rural places and margin points. And considering the construction in the margin of this city caused the negligence of experts to the renovation and restoration of damaged and central textures of Shiraz for the reason that these textures are the main problems of urban management which it [problem] was considered as the most important concept by the urban experts of Iran during the recent year in particualr the first half of 80 decades [after bam earthquake].In this article, in order to study the experiences of Iran and the world, the theoretical points related to the importance of earthquake in the urban ancient and damaged textures were analyzed and finally, the indexes for determining the susceptibility of an ancient or damaged texture were defined. These indexes are the basis of our recognition to the considered are [Shiraz-Zulanvar area] and the level of its susceptibility [susceptibility of a texture] is based on each of them as well, by determining their effective coefficients, the whole susceptibility of different points was specified. This information is the basis of programming / planning to reduce the level or quantity of susceptibility and present the required suggestions.
