A framework for quantitatively evaluating the seismic resilience of hospital systems is proposed, which categorizes a typical hospital system and quantifies importance factors for different functional units, subsystems, and components. Seismic resilience is quantified based on probabilistic seismic fragility analysis, and recovery time is calculated considering an idealized repair path. The loss of functionality of the hospital is evaluated by summing the weighted economic losses of all components. A case study of a hospital building is conducted to demonstrate the feasibility and effectiveness of the proposed framework.
A framework to quantitatively evaluate seismic resilience of hospital systems is proposed. A typical hospital system is categorized and importance factors for different functional units, subsystems, and components are quantified. Resilience demand is expressed as desirable recovery time of hospital system after earthquakes. Seismic resilience is quanti?ed based on probabilistic seismic fragility analysis. Recovery time is calculated considering an idealized repair path. Loss of functionality of the hospital is evaluated as sum of weighted economic losses of all components. Case study of a hospital building was performed to demonstrate the feasibility and effectiveness of the proposed framework.
