Based on the ANSYS finite element software,the analysis of the hysteretic behavior of BRBs was done and compared with the hysteretic behavior of ordinary braces in this paper.The study focused on the seismic responses of the steel frame with two different seismic waves,and the results showed that when the BRBs were applied into the steel frame,the intensified stiffness and energy dissipation ability of the steel frame would be greatly improved.%基于ANSYS有限元软件,对屈曲约束支撑的滞回性能进行了分析,并与普通支撑的滞回性能进行对比.采用两种地震波研究钢框架的地震响应,结果表明：相对于普通支撑而言,屈曲约束支撑能进一步提高钢框架的后期刚度和耗能能力.
