رتبه بندی تاب آوری کالبدی فضایی مناطق شهری (مطالعه موردی: کلان شهر کرج)

یکی از ارکان مهم تاب آوری در سیستم های شهری مفهوم ابعاد کالبدی تاب آوری است که به طور سیستماتیک عناصر و ساختار کالبدی را مورد تحلیل قرار می دهد.هدف از این تحقیق رتبه بندی تاب آوری کالبدی مناطق شهری کلان شهر کرج بر پایه مدل الکتر است. روش تحقیق توصیفی – تحلیلی بوده است قسمتی از داده های پژوهش از طرح جامع و تفصیلی در قالب، سیزده گویه از مولفه های کالبدی فضایی برحسب نظرات کارشناسی و تکنیک سلسله مراتبی انتخاب شدند. و مابقی اطلاعات از طریق مطالعه کتابخانه ای، اسنادی و پیمایشی به وسیله ابزار پرسشنامه و مصاحبه حضوری جمع آوری، سنجش و ارزیابی شده است.اطلاعات مورد نیاز پژوهش بعد از استخراج با استفاده از نرم افزار آماری spss از طریق روش های آماری ناپارامتری و روش الکتر از نظر تاب آوری کالبدی رتبه بندی و تجزیه و تحلیل شده است نتایج نشان می دهد که در مجموع مناطق یک، هشت، هفت و نه به دلیل نظام قطعه بندی نسبتا منظم و عرض استاندارد معبرو کیفیت عمومی بناهای موجود دارای بیشترین تاب آوری کالبدی هستند و مناطق 11 و 12 و قسمت هایی از محلات اسلام آباد و میدان کرج به دلیل پخشایش ناموزون فضای باز و محصوریت معابر عمومی دارای نزولی ترین رتبه در تاب آوری کالبدی می باشند

ranking of the spatial resilience of karaj metropolitan

introduction the disasters that have taken place in recent years have shown that societies and individuals are increasingly vulnerable and have increased risks. however, risk and vulnerability reduction is often ignored until after the accident. often, a natural disaster is associated with the destruction of income and biological resources, the health of residents, especially children and the elderly, and is always a serious risk to development, especially in developing countries. iran is among the countries with a high degree of vulnerability to natural disasters due to geographic and geological conditions. so that 31.7% of its total area is located in areas at risk of natural disasters and 70% of the population lives in areas at risk of natural disasters. the metropolis of karaj with a population of more than one million and an area of 13036 hectares, with a migration rate of about 2.8 in the period of 1390-1373 and a population density of 195 people per hectare, as a service center in alborz province. the main purpose of this paper is to explain and evaluate the physical resilience capacity of the 12th metropolitan areas of karaj using the electre method. and what is the difference between the electre methodology and the ranking of regions? methodology regarding the components of the study, the prevailing approach to this research is descriptive and analytical. the statistical population of the present study is twelve regions of karaj in 1395. a questionnaire was designed to investigate physical resilience. according to the cochran formula, with 95% confidence interval, 352 questionnaires were distributed randomly in a simple random sampling method and distributed to the population of each region in 12 provinces of karaj. cronbach's alpha coefficient was calculated for 30 questionnaires of 0.843, which indicates its high reliability and weighted the indices and in order to classify urban neighborhoods, electrothermal techniques have been used. the process of data processing is also done in excel software. in this research, in order to operationalize the research variable, according to the data in the comprehensive and detailed design, among the indicators obtained and a wide range of effective criteria, eight spheres have been selected from the physical-space components and have been used in the research. results and discussionthe analysis of the data shows that the physical condition of the 12th district of karaj, with respect to the resistance index of building structures, is due to the existence of worn out textiles including 11,12 districts, including high and low clocks, 400 units and agh tape with 1.87 and 1.9, respectively, have the least amount of resiliency and have the last rank among the areas in terms of the structure of the structure. due to the information it adds about the unfavorable conditions of building quality, such as the gender and strength of building structures. so that more than 65% of the structures of the above mentioned areas are irrelevant. therefore, in the event of an earthquake, it is possible to disconnect from other urban areas in these areas and
