Abstract
Introduction: Investigating the resilience of cities to earthquakes is one of the most important planning requirements for reducing earthquake loss in cities. Resiliency has different definitions and there is no comprehensive model to calculate it. Therefore, one of the purposes of this paper is to provide a quantitative indicator for resilience.
Method: For this purpose, first, using library studies and obtaining expert opinions, the dimensions and effective indicators in earthquake resiliency have been extracted. Then, using the experts' opinion and the method of pair comparison, the weight of each of the dimensions and indicators was determined. At the end, the index of resiliency is introduced.
Results: In this paper, while introducing a summary of the definitions of disasters and resilience, the dimensions and indicators derived from past studies and expert opinions were introduced. These dimensions and indicators represent the factors that affect urban resilience against earthquakes. Accordingly, the body dimension, which represents the structure of the city, has the largest share in the city's resilience to the earthquake. After that, security is the most important factor in urban resilience. Regarding the indexes, in the physical dimension, the index "building height / width ratio" has the most impact on the urban resilience against the earthquake. The number of construction floors has a slight impact on other indexes. Because when constructed using a suitable structure, there is not enough room for adequate access to the passageways, the number of building floors is not very important for vulnerability.
Conclusions: The index is introduced can be computational resiliency for different cities as well as various strategies for retrofitting. Thus, it is possible to select the optimal strategy in terms of the resilience. Planners and decision-makers are also able to see the effects of various aspects on the resilience of the city or region under study.
