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。
Through the experimental research on the restrained buckling brace with contact ring double steel tube, the influence of bearing capacity under load under one-way load, the change law of load-displacement curve, the outer sleeve clearance and the outer sleeve stiffness on the mechanical properties were discussed. The finite element simulation results are compared with the theoretical calculation results and the test results to grasp the strength and energy dissipation characteristics of the members, which can provide useful reference for restraining the application of buckling support in the structure.
