Abstract

Earthquake, regardless of being a natural phenomenon, throughout history has had another characteristic: being a disaster. The present dissertation (briefly including objectives, methods of implementation and results) has tried to provide an answer to this question that how urban development knowledge, as an interdisciplinary knowledge could reduce physical damage caused by earthquakes in urban areas? The answer to this question has been explored by emphasizing on urban fabric and considering the following hypotheses:
Hypothesis 1: It seems that urban fabric is effective in reducing or increasing physical damage caused by earthquake.
Hypothesis 2: It is expected that regular fabric (checkered) could stand less vulnerable to earthquake as compared to organic texture.
After reviewing scientific sources and international experiences, and selecting research indices, that is to say building features (number of stories, quality of the building, quality of materials and structures), land segmentation (discipline of the texture, ratio of site to superstructure, area of the piece, quality of road network (discipline of the road network and width of the road), distance from the fault and distance from open air, questionnaire was used with the help of SPSS software for the first hypothesis testing. Then the results obtained through analytic model of the research in the two areas, namely with checkered fabric (Shahrak-e Gharb) and organic texture (Darakeh) were applied by using a combination of AHP technique and GIS software through JICA studies for the second hypothesis testing. The final result indicates that urban texture as the foundation of the city has remarkable effect on the extent of vulnerability of the city against earthquake. Despite the role that characteristics of a building plays, the more regular the land segmentation; the more access to open air and passages six meters plus; and the more distance to the fault and the less the ratio of the site to superstructure, it could be said that vulnerability of segments to earthquake would be lesser.
