摘　　要：防屈曲约束支撑(BRB)性能稳定,滞回耗能好,受外界环境影响小,更换方便,价格便宜,是目前一种常用的减震阻尼器。本文以某钢框架结构的减震设计为例,研究比较了设置防屈曲约束支撑后,结构的地震响应。研究结果表明:屈曲约束支撑提高了小震时主体结构的刚度,增大了罕遇地震时的耗能,具有较好的抗震耗能机制,有效提高了主体结构的安全性。The BRB has stable performance and good hysteresis energy consumption, the external environmental has few impact on it,it is easy to replace and it is cheap, so it is a kind of commonly used damper. In this paper, the seismic design of a steel frame structure is studied, and the seismic response of the structure after the BRB is set. The results show that the BRB improves the stiffness of the main structure in the small earthquake, increases the energy consumption in the rare earthquakes, and it has good anti-seismic energy dissipation mechanism and is effectively improves the safety of the main structure.
