This study focuses on the seismic performance of soft-first-story buildings, which are demanded especially in urban areas. Six-story reinforced concrete buildings are studied, and the seismic responses of the soft-first-story structures and typical frame structures are statistically assessed based on the results of dynamic response analyses. The mean annual frequencies of the maximum interstory drift ratio exceeding the specified values are computed and shown as drift hazard curves. Finally the probabilities of the structures exceeding the safety limit states in 50 years are computed and compared.
