This paper presents a framework for decision-making regarding post-earthquake\nassessment of instrumented buildings in a manner consistent with\nperformance-based design criteria. This framework is achieved by simultaneously\ncombining and advancing existing knowledge from seismic structural health\nmonitoring and performance-based earthquake engineering paradigms and consists\nof 1) optimal sensor placement, 2) dynamic response reconstruction, 3) damage\nestimation, and 4) performance-assessment and decision-making. In particular,\nthe main objective is to reconstruct inter-story drifts with a probabilistic\nmeasure of exceeding performance-based acceptance limits and determining the\npost-earthquake re-occupancy classification of the instrumented building of\ninterest. Since the proposed framework is probabilistic, the outcome can be\nused to obtain the probability of losses based on the defined decision\nvariables and be integrated into a risk-based decision-making process by city\nofficials, building owners, and emergency managers. The framework is\nillustrated using data from the Van Nuys hotel testbed, a seven-story\nreinforced concrete building instrumented by the California Strong Motion\nInstrumentation Program (Station 24386).\n
