论文摘要
本文介绍了一个与基于绩效的设计标准一致的方式进行仪器建筑物评估的决策框架。该框架是通过同时结合和促进现有知识从地震结构健康监测和基于绩效的地震工程范式中实现的，由1）组成1）最佳传感器放置，2）2）动态响应重建，3）损害估计，4）绩效评估和决策。特别是，主要目的是通过概率度量重建阶层的漂移，以超过基于绩效的验收限制并确定仪器的利益构建的地球后重新占领分类。由于提出的框架是概率的，因此结果可用于根据定义的决策变量获得损失的可能性，并将城市官员，建筑所有者和紧急事务经理人集成到基于风险的决策过程中。使用Van Nuys Hotel Testbend的数据进行了框架，该框架是由加利福尼亚强大的运动仪器计划（Station 24386）的七层钢筋混凝土建筑仪器。
This paper presents a framework for decision-making regarding 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 and consists of 1) optimal sensor placement, 2) dynamic response reconstruction, 3) damage estimation, and 4) performance-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 determining 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 (Station 24386).
