摘      要：Existing buildings can be at a greater seismic risk due to non-conformance to current design codes and may require structural retrofitting to improve building *** performance of buildings is measured in terms of immediate consequences due to direct damage,but the continuing impacts related to recovery are not considered in seismic retrofit *** paper introduces a framework of retrofit selection based on the seismic resilience of deficient buildings retrofitted with the conventional mitigation *** assembly-based methodology is considered for the seismic resilience assessment by compiling a nonlinear numerical model and a building performance *** collapse fragility is developed from the capacity curve,and the resulting social,economic,and environmental consequences are *** seismic resilience of a building is assessed by developing a downtime assessment methodology incorporating sequence of repairs,impeding factors,and utility *** functionality states are developed for the building functionality given investigated time interval,and a functionality curve for each retrofit is *** is concluded that seismic resilience can be used as a performance indicator to assess the continuing impacts of a hazard for the retrofit selection.
