高层钢结构中框架—支撑结构是一种常用的结构形式,文中介绍了支撑结构体系的发展情况.以某实际工程为例,说明了普通钢支撑和屈曲约束支撑两种不同支撑对结构弹性性能的影响,通过静力弹塑性推覆分析对比研究了两种方案的弹塑性性能,并对屈曲约束支撑采用偏心布置形式对框架梁的影响进行了探讨.%Braced steel frame is a normal structural system in high-rise steel buildings. The development of the braced steel frame is introduced. Based on a practical project, the influences of steel braces and bucking restrained braces on the elastic and elasto-plastic behavior are analyzed. By pushover analysis, the seismic behaviors of two frames are studied. And the buckling restrained braces used in eccentrically braces steel frames are analyzed.
