Abstract
Iran is considered one of the most seismic countries in the world due to its location in the Alpine-Himalayan seismic zone, its geological and tectonic location, the presence of numerous active faults in its various parts, and the continuous occurrence of micro-earthquakes. After the occurrence of destructive contemporary earthquakes in Iran and the extensive destruction of urban and rural housing, various approaches have been taken into consideration by planners and policymakers in order to rebuild housing after the disaster. The purpose of this article is to evaluate the correct and optimal management of housing reconstruction after an earthquake in four earthquakes that occurred in Iran, namely the Rudbar-Manjil earthquake (1369), the Bam earthquake (1382), the Ahar-Varzaghan earthquake (1391), and the Sarpol-e Zahab earthquake (1396). The basis of the evaluation in this article is the "Management cycle of housing reconstruction after the earthquake" model, which includes four main criteria groups and 17 weighted criteria. These factors play an effective role in reducing financial, managerial, and executive problems and achieving desired results in optimal reconstruction. The criteria are categorized in 4 main groups of “Coordination and organizational affairs”, “Technical and engineering affairs”, “Economic and financial affairs”, and “Social participation and community affairs”. Prioritized by experts, the factors of “Economic and financial affairs” and “Coordination and organizational affairs” are recognized as the most influential, followed by the next priorities, “Technical and engineering affairs” and “Social participation and community affairs”.
In this research, the quantitative evaluation is in the form of a questionnaire through a survey of the community of experts and specialists. In this way, 68 experts in the field of post-disaster reconstruction from different organizational, academic, and engineering levels participated in this evaluation based on the AHP method.
The interviewees were asked to categorize their opinion on the level of realization and implementation of 17 effective criteria in post-disaster housing reconstruction during the selected earthquake reconstruction program in five qualitative levels (from 1 to 5). In this survey, score 1 indicates the lowest degree of realization of the criterion, and score 5 indicates the highest degree of realization of the post-accident reconstruction criterion. The answers given to each question were averaged. After conducting statistical analysis and investigations on the results of participants' opinions in the form of two questionnaires, the performance of housing reconstruction in each of the four selected earthquakes is close to each other in the range of 0.4 to 0.5. That is, there has been no significant progress in reconstruction since the Rudbar-Manjil earthquake to Sarpol-e Zahab. The Ahar-Varzaghan earthquake of 2011, with an average score of 0.470, had the best performance, and the Sarpol-e Zahab earthquake of 2016 with an average score of 0.415 had the weakest reconstruction performance among other disasters. Of course, with careful analysis and calculations, it was observed that the opinions of the respondents were closer to each other in Ahar-Varzaghan, and the dispersion of opinions was greater in Sarpol-e Zahab.
