摘　　要：屈曲约束支撑的滞回曲线饱满,具有较好的抗震性能,用于结构抗震加固更显优势。通过对玉溪一中教学楼采用屈曲约束支撑进行抗震加固的介绍,说明了采用屈曲约束支撑加固结构体系的分析方法。在此基础上对该加固结构进行反应谱分析及时程分析。分析结果表明,加固后结构的抗震性能得到了极大改善,结构的抗震能力显著提高。Buckling restrained braces, which have full hysteresis curves and well seismic performance, have more advantages in structural seismic reinforcement. The application of buckling restrained braces in the seismic strengthening engineering of Yuxi No. 1 middle school teaching building was introduced to illustrate the analysis method of the structural system strengthened by buckling restrained braces. On this basis, response spectrum analysis and time-history analysis were carried out on the strengthened structure. Analysis results show that the seismic performance of the strengthened structure is greatly improved, and the seismic capacity is increased significantly.
