Abstract: The fundamental mechanism, categories and advantages of BRB( buckling restrained brace) are carefully illustrated through its application in a high-rise steel residential structure. The elastic analysis under frequently occurred earthquake, and elasto-plastic time lustory analysis under rarely occurred efuthquake are taken. In regions of high seisnuc intensity, adapting BRB in the high-rise steel structures can greatly improve its energy-consuming quality. Thus the overall yielding mecharusm is good. It is believed that BRB has a wide-range application prospect.
