Abstract

In order to overcome the negative effects of the disasters, buildings, infrastructures and more generally, communities, are better to react resiliently. As an illustration of the concept of resilience, seismic resilience is referred to as the ability of a system to reduce the chance of a shock, to absorb such a shock and to recover the system after the disaster as soon as possible. The resilience of structures has gained its initial approach from a more general and broader definition, and due to that, further engineering concepts have been formulated. Physical quantification of the resilience involves the probability of exceedance of the floor acceleration or drift from a certain limit. For this purpose, nonlinear response of the structures as well as the effect of rehabilitation, repair and recovery time of the structure, and following to that communities, are used. This proposed framework relates the probability function, failure and resilience as a continuous approach. In this paper, we try to introduce a characteristic called the communities resilience index, by which the performance of various communities is calculated and compared by the PEOPLES framework.
