The paper is concerned with loss estimation analysis of flat-slab structures, a reinforced concrete structural form that exhibits behavior and response patterns distinct from conventional moment frames. The fragility information obtained for flat-slab structures presented in a companion paper is implemented into HAZUS, the loss assessment software of the Federal Emergency Management Agency. The latter program includes many existing structural types, but does not deal with flat-slab structures. For implementation purposes, the fragility curves should be in a format consistent with fragilities already available in HAZUS. The latter objective is achieved by making use of the response statistics and employing the capacity spectrum method. After implementation, the earthquake losses in flat-slab buildings are predicted in comparison with the existing structural types in HAZUS by using different scenario earthquakes for a selected study region. The prediction results are consistent with the seismic response characteristics of the compared structural types.
