ABSTRACT

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 quantified 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.

摘要

提出了一种定量评估医院系统抗震能力的框架。对典型的医院系统进行分类，并对不同功能单元、子系统和组件的重要性因素进行量化。弹性需求表示为地震后医院系统的理想恢复时间。地震弹性是基于概率地震脆弱性分析来量化的。恢复时间的计算考虑了理想的修复路径。医院的功能损失被评估为所有组成部分的加权经济损失的总和。进行了医院建筑的案例研究，以证明拟议框架的可行性和有效性。
