摘　　要：屈曲约束支撑在拉力和压力的作用下都能屈服而不屈曲,具有良好的滞回性能,且安装方便,因此被广泛应用于加固改造项目中。本文分析了既有建筑需要加固的原因,并结合实例总结了屈曲约束支撑在加固改造工程项目中应用的优势。Buckling restrained brace can yield in both tension and compression without buckling,performs good hysteretic properties,and it is easy to install,so it is widely applied in strengthening projects. This paper analyzes the reasons why existing buildings need to be strengthened,and concludes the advantages of buckling restrained brace applied in the strengthening projects through several examples.
