Title

Study of the Effectiveness of "Technical-Physical" and "Socio-Economic" Strategies in Improving Urban Resilience against Earthquakes

Pages

  99-114

Abstract

 There is no comprehensive model for quantitative calculation of resiliency. To this end, using documentation studies and expert opinions, the Conceptual model of the resiliency of cities against earthquakes were extracted. It is considered that resiliency has social, economics, technical, physical, institutional, and security dimensions. The 6th municipal district of Tehran was considered as case study. Using the proposed index and considering three seismic scenarios, the effectiveness of technical-physical and socio-economics strategies in improving the resiliency of the studied district were compared. In order to better compare strategies, the costs of implementing strategies and the time span of their implementation are also estimated. The weights of social, economic, technical, physical, institutional, and security dimensions were 0. 198, 0. 153, 0. 136, 0. 202, 0. 151 and 0. 159, respectively. The value of the resiliency index is 0. 458, 0. 454 and 0. 456 in North-Tehran fault, Ray fault the floating scenario, respectively. At the best case, the S3 strategy improved the RI by about 33% in all the three assumed seismic scenarios. The T3 strategy for the case of the North Tehran fault scenario improved RI by 31% and in other two seismic scenarios, the improvement was about 28%. S3 strategy is the best strategy for increasing the overall resiliency index considering the cost of implementation as decision measure and the weakest strategy is T1 in this regard. Nevertheless, in terms of the time span as decision measure T1 is the optimal strategy. In the short run, T1 and, in the long run, S2 are the best strategies.
