摘　　要：为了研究含有屈曲约束支撑结构的抗震性能,对含有屈曲约束支撑和普通支撑的平面框架进行了试验研究。结合试件破坏现象及试验结果,对屈曲约束支撑的力学性能、破坏机理以及作用效果进行了分析探讨。同时,还对试验过程进行了数值模拟分析。试验及理论分析结果表明:与含普通支撑框架相比,含屈曲约束支撑的框架在提高承载力的同时,还具有更稳定的耗能能力;经过适当的设计,可以使屈曲约束支撑先于主体结构进入弹塑性状态,提高结构的抗震性能。In order to study the seismic behavior of structure with buckling-restrained braces（BRB）,a buckling-restrained braced frame（BRBF） and a conventional braced frame（CBF） were tested by low-reversed cyclic loading.Based on the phenomenon and results of BRB and BRBF,the damage mechanism of BRB and BRBF,the measured and theoretical mechanical properties of BRBF and CBF were analyzed and discussed.The results indicate that BRBF has better bearing capacity and energy dissipation characteristics than CBF.Through the proper design,BRB can get into elasto-plastic stage while the main frame is still in elastic stage,and the seismic behavior of main frame can be raised by the energy dissipation of BRB.
