摘　　要：约束屈曲支撑是一种性能优良的新型耗能减震构件,在承受拉力和压力时,表现出良好的滞回性能和耗能能力,具有广阔的应用前景。阐述了约束屈曲支撑的构成和基本原理,并通过ANSYS有限元软件对设有约束屈曲支撑并有局部收进的高层钢结构相关工程进行了耗能减震性能分析。A buckling restrained brace is a new-type vibration-reducing component,which is fairly hyster- etic and energy-dissipating under tension and pressure,having broad applications. The composition and bas- ic principle of a buckling restrained brace was expounded and the seismic effects of the buckling restrained brace on the local narrowing high--rise steel frame in high intensity earthquake areas were analyzed through the finite element software ANSYS.
