ABSTRACT

In this chapter, a framework to quantitatively evaluate the seismic resilience of hospital systems is proposed. A typical hospital system is categorized into five functional units and seven subsystems. Each subsystem contains several components to support the functionality of the subsystem. A weighting coefficient called the importance factor for each functional unit, subsystem, and component is proposed. With these quantified importance factors, the resilience demands on the emergency and the complete functionalities can be evaluated by a system analysis method that is expressed as the desirable recovery time of a hospital system after an earthquake. Subsequently, the seismic resilience of the hospital system is quantified based on the individual component fragility within the proposed framework and using a probabilistic seismic fragility analysis. As one of the most important indices, the recovery time is calculated and is based on the recovery time of each damaged component and summed for all components considering an idealized repair path. Finally, the loss of functionality of the hospital can be evaluated as the sum of the weighted economic losses of all components. The case study of a reinforced concrete hospital building was performed to demonstrate the feasibility and effectiveness of the proposed framework.
