Recently, a steel damper is widely used among energy dissipation devices for seismic retrofit, a steel damper has many advantages than other types of seismic control devices. It can be easily manufactured based on the design specification, and it can dissipate a lot of seismic energy through the stable hysteresis behavior of steel. In this study, in order to obtain more effective energy dissipation capacity than general types of steel dampers, the yield strength of steel with different section properties were used as variables. For this purpose, steel dampers were manufactured using two types of steel dampers with relatively different section properties. As a result, the steel with relatively low section property first yielded and the steel with high section property progressively yielded. Finally, it effectively responded to various range of lateral load and showed good performance with respect to the ductility.
