This paper develops a decision making framework for post-earthquake assessment of instrumented buildings in a manner consistent with performance-based design criteria. This framework is achieved by simultaneously combining and advancing existing knowledge from seismic structural health monitoring and performance-based earthquake engineering paradigms. The framework consists of (1) measurement, (2) uncertainty modeling, (3) dynamic response reconstruction, (4) damage estimation, and (5) performance-based assessment and decision making. In particular, the main objective is to reconstruct inter-story drifts with a probabilistic measure of exceeding performance-based acceptance limits and determine the post-earthquake re-occupancy classification of the instrumented building of interest. Since the proposed framework is probabilistic, the outcome can be used to obtain the probability of losses based on the defined decision variables and be integrated into a risk-based decision making process by city officials, building owners, and emergency managers. The framework is illustrated using data from the Van Nuys hotel testbed, a seven-story reinforced concrete building instrumented by the California Strong Motion Instrumentation Program (CSMIP Station 24386).

基于性能的仪表楼地震后决策

本文以与基于性能的设计标准相一致的方式,为仪表建筑物的地震后评估制定了决策框架。该框架是通过同时结合和推进地震结构健康监测和基于性能的地震工程范式中的现有知识来实现​​的。该框架包括(1)测量,(2)不确定性建模,(3)动态响应重构,(4)损害估计以及(5)基于性能的评估和决策。特别是,主要目标是重建具有超过基于性能的验收限制的概率测度的层间漂移,并确定感兴趣的仪器建筑物的震后重新占用分类。由于建议的框架是概率性的,结果可用于根据定义的决策变量获得损失的可能性,并由城市官员,建筑物所有者和紧急情况管理者集成到基于风险的决策过程中。使用来自Van Nuys酒店测试台的数据对框架进行了说明,该测试台是由加利福尼亚强运动仪器计划(CSMIP Station 24386)安装的七层钢筋混凝土建筑。
