摘　　要：防屈曲耗能支撑既能提供刚度,又具有良好的耗能能力,因此在结构抗震设计中常被采用。本文以昆明某中学教学楼工程为例,研究了设置防屈曲耗能支撑后,结构的地震响应。研究结果表明:在附设了防屈曲耗能支撑后,结构具有了良好的抗震耗能机制,结构主体的安全性得到提高。Buckling-restrained brace not only can provide stiffness for the structure, but also has a good energy dissipation capacity, so it is often taken for the seismic design of engineering structures. This paper took a middle school teaching building engineering in Kunming as an example, and studied the seismic response of the structure that adopted buckling restrained brace. The results show that the at- tachment of buckling restrained brace make the structure have a better seismic energy dissipation mecha- nism, and additionally, the safety of the main structure has a great imorovement.
