ارزیابی عوامل درونی تاثیرگذار در آسیب پذیری ساختمان های شهری در برابر زلزله با استفاده از GIS(نمونه موردی :بافت قدیم شهر خوی)
The Assessment of Internal Effective Factors in Urban Building Vulnerability in Earthquake Against Using GIS (A case Study: old texture of Khoy city)
The old texture of Khoy city is consistent with the historic core and central city. There are elements of the traditional market, mosque, etc. which are the most important historical and cultural identity indicators in this region. Today, the historical texture has big problems with the use of non-resistant materials, lack of penetration into the organic texture, poor quality buildings and small packs. According to previous earthquake records in Iranian cities such as Bam, it is shown that human casualties and physical damage in old texture is higher than other urban areas. Therefore, vulnerability zoning of this region caused identifying needs and acting to before disasters. In this research old texture of Khoy city (Region 1) with considering internal effective factors in housing vulnerability in earthquake against such materials, antiquity buildings, old buildings, number of floors, land use,occupied surface, area of packs, positioning building in blocks, number of neighboring packs, soil type, slope and shape of the pack using AHP in Arc/GIS software has been assessed. The results show that 0.39% of building has very high vulnerability, 19.66% high,73.3% medium and 6.61% low vulnerability.
