摘　　要：通过对带接触环双钢管约束屈曲支撑的试验研究,讨论了支撑在单向加载下的承载能力、荷载位移曲线变化规律,外套管间隙、外套管刚度对受力性能的影响。并将有限元模拟结果与理论计算结果和试验结果进行对比分析,掌握构件的强度和耗能特性,为约束屈曲支撑在结构中的应用提供有用的参考意见。In this paper through the experiment study on the Double-tube BRBs,the carrying capacity and the relations between load and displacement are gained.At the same time,the hysteretic behavior of BRBs and its relationship with the stiffness of outer-tube and the clearance are discussed.The results of numerical simulation and the ones of theoretical calculated and experiments are compared,and the strength and energy dissipation characteristics of BRBs are mastered.In this way,useful suggestions about the application of BRBs are provided.
