Analysis of effective factors in achieving the principles of passive defense in regeneration projects using contextual theory (case study: Qarchak city)

Urban regeneration from the point of view of non -active defense means reducing the vulnerability of buildings, facilities, equipment and urban and regional arteries through natural hazard management and social mobilization (popular participation) in reducing damages related to inefficient tissues. Be In this regard, the aim of the present study is to analyze the effective factors in achieving the principles of passive defense in the regeneration plans of Qarchak city using grounded theory. In terms of the purpose, the current research is part of the fundamental and descriptive researches, and in terms of the method, it is included in the group of qualitative researches. The sample size for interviewing experts in the framework of final theoretical saturation using targeted sampling, 18 experts (experts, university professors and city managers of Qarchak) were selected. The grand theory method was also used to analyze the data. The result of interviews with experts to analyze the effective factors in achieving the principles of passive defense in regeneration plans in Qarchak city using contextual theory, including 6 core codes (causal, contextual, intervening, strategic conditions) consequences and obstacles). Causal conditions from 5 categories and 16 concepts, contextual conditions from 4 categories and 15 concepts, intervening conditions from 5 categories and 13 concepts, strategies from 3 categories and 11 concepts, consequences from 5 categories and 14 concepts, and finally, the obstacles consist of 7 categories and 17 concepts.
