The conventional braced system is generally accepted as the lateral load resisting system for steel structures due to efficient story drift control and economic feasibility. But lateral stiffness of the structure decreases when buckling happens to the brace in compression, so that it results in unstable structure with unstable hysteresis behavior through strength deterioration. Buckling restrained brace(BRB) system, in which steel core is confined by mortar/concrete-filled tube, represents stable behavior in the post-yield range because the core"s buckling is restrained. So, seismic performance of BRB is much better than that of conventional braced system in point of energy absorption capacity, and it is applied the most in high seismicity regions as damper element. In this study, we examined a few of weaknesses of general-shaped BRB and improved them, so that suggested new shape of BRB. It is made up of two steel restraining elements with non-filled material and the steel core. The new shapes of BRB were tested according to AISC(2010) and evaluated seismic performances and hysteresis characteristics.
