摘　　要：以一个单跨不规则框架结构为例,分别采用钢支撑加固和抗震墙加固方案,对原结构和加固后结构进行弹性以及弹塑性对比分析,分析结果表明:两种加固方案均能调整结构扭转特性,有效提升结构抗震性能。In the paper, the retrofitting scheme of an irregular single-span frame is designed with adopting two scheme： one is applying steel brace, and the other is adding seismic wall. The results show that the torsion property and seismic performance of irregular single-span frame with the presented scheme can be improved distinctly under elastic and elastoplastic analysis.

关 键 词：单跨不规则框架 抗震墙 钢支撑
