The authors have proposed mid-floor leveled column base system. The first story columns consist of the reinforced concrete downside column and the steel topside column, and their joints with the anchor bolts and the shear plates are supposed to be pinned. In this paper, the building designed by using mid-floor leveled column base system of applicability and seismic performance are studied. In order to compare mid-floor leveled column base system and conventional column base system, the building designed by using exposed type column base and embedded type column base are studied.
