This paper introduces a framework to link the seismic performance of buildings with community resilience, and proposes a novel long-term resilience indicator that integrates different magnitude earthquake probabilities. The framework is effective in assessing whether the desired community resilience goals can be achieved by evaluating the seismic performance of buildings and highlights the importance of considering the interdependence between infrastructure systems.
Due to the great human and social impacts of natural hazards, the concept of community resilience has gained unprecedented attention across multiple disciplines in the last decade. While most studies focused on the assessment and quantification of community resilience, there is a lack of research on how to incorporate the probabilistic seismic performance, which is obtained from performance-based earthquake engineering (PBEE), of individual buildings into the assessment. This manuscript presents a framework to bridge the gap between seismic performance of buildings and community resilience. In addition, a novel long-term resilience indicator integrating the probability of earthquakes with different magnitudes is proposed. The framework can be used to assess if the desired community resilience goals can be achieved by evaluating the seismic performance of buildings and other infrastructure systems. To explicitly account for the interdependence of different infrastructure systems during the restoration process, a network-based recovery model is established. The framework is illustratively applied to a community consisting of buildings, power distribution system, and transportation system by performing a large number of post-earthquake recovery simulations. The simulation results demonstrate that the framework is effective to link the proposed long-term resilience indicator to the seismic performance of individual buildings and it highlights the importance of considering the interdependence between infrastructure systems in community resilience assessment.
