This report shows the advantage of using high-strength steels and hysteretic dampers for low- and medium-rise buildings. In this paper, the structural members are decided by the long term stress. Seismic loads are burdened with hysteretic dampers. There are two methods to increase the yield stress of columns; one is using high-strength steels, and the other is adopting larger members. Through the investigation of time history response analysis, a method using high-strength steels has high performance not only decreasing damage of frame but also increasing the equivalent damping factor than another method.
