Abstract


A risk management model was applied to residential wooden structures in earthquake-prone areas of Iran. The statistical population of the study consisted of academic and organizational experts. Thirty individuals were interviewed using a purposive non-random sampling technique and the data adequacy and saturation principle. A semi-structured interview was used to collect the required data. The validity was assessed using content and construct validity. Cronbach's alpha coefficient was used to measure reliability, and it was greater than 0.7 for all components. In the qualitative section, data analysis was performed via a theoretical coding method that used the Grounded Theory approach, and the model was presented using interpretive structural modeling. The results revealed that the dimensions of the seismic related risks in the implementation of wooden residential structures in earthquake-prone areas of Iran, which included the internal risks (employer risk, implementation risk, scheduling risk, manpower risk, and design risk) and the external risk (risk due to political, economic, legal, and natural factors), were the most important risks.
