This paper discusses the seismic performance of buildings which stories are subtracted through time history analysis. Target buildings have stories ranging from five to fourteen and are office, hotel, and residential complex. A practical evaluation method of the maximum inter-story drift is proposed for reinforced concrete buildings which stories are subtracted. Its required information is an elastic natural period of buildings, a predominant period of ground motion, and a target ductility factor. With this method, convenient required number of stories is computed so as to mitigate the maximum inter-story drift.
