地震或其他灾害事件后的建筑物损坏可能会中断业务，使家庭流离失所，并严重扰乱社区多年。因此，政策制定者和工程师正在努力制定新的设计准则和政策，通过改善建筑功能恢复性能来减少建筑环境的脆弱性。本研究提出了一种方法，用于评估地震后的建筑性能状态的功能和reoccupancy内的建筑性能为基础的地震工程，针对美国的建设，利用联邦应急管理局（FEMA）P-58脆弱性和后果模型。这是通过将组件损坏状态映射到系统级操作性能，然后通过一系列故障树映射到建筑物级性能状态来实现的。该研究还提出了一种修复调度算法，以估计所需的时间来恢复建筑物的占用或功能，考虑阻碍因素，延迟开始维修。其结果是一个概率的方法，扩展了基于性能的工程框架，明确量化震后建筑功能的性能状态，从而促进设计和缓解决策的恢复为基础的性能目标。
Building damage after an earthquake, or other hazard event, can interrupt businesses, displace households, and significantly disrupt a community for years. As a result, policymakers and engineers are working toward new design guidelines and policies that reduce the vulnerability of the built environment through improved building functional recovery performance. This study proposes a method for assessing post-earthquake building performance states of function and reoccupancy within the architecture of performance-based earthquake engineering, targeted at US construction, making use of Federal Emergency Management Agency (FEMA) P-58 fragility and consequence models. This is accomplished by mapping component damage states to systems-level operational performance, and then to building-level performance states, through a series of fault trees. The study also proposes a repair scheduling algorithm to estimate the time taken to restore building reoccupancy or function, considering impeding factors that delay the start of repairs. The result is a probabilistic approach that extends the performance-based engineering framework to explicitly quantify post-earthquake building function performance states, thus facilitating design and mitigation decisions for recovery-based performance objectives.
