Hospitals play a crucial role in the mitigation and recovery of earthquake-hit regions, which are expected to be resilient enough so as to provide medical care that is badly needed in the aftermath of earthquakes. Nevertheless, there lack appropriate quantitative assessment approaches of hospital earthquake resilience, which makes it challenging for devising and benchmarking resilience enhancement measures. In this paper, a quantitative assessment approach of hospital resilience to earthquakes considering the physical damage and the recovery of hospital functionality is proposed. A system dynamics (SD) model is developed to simulate the hospital functionality hence enabling quantification of hospital resilience to earthquakes. The efficacy of the proposed approach is validated in a case study. The proposed approach can provide a tool for hospitals to quantitatively assess their resilience to earthquakes so as to propose targeted resilience enhancement measures for future earthquakes.
