摘要

通过对外联式矩管柱与H形钢梁节点的低周往复加载试验,阐述了其破坏过程和破坏机理,获得了节点的滞回曲线和极限承载力。同时利用ABAQUS对试验进行了模拟分析,计算结果与试验吻合良好;讨论了钢梁翼缘、腹板厚度及矩管柱壁厚对钢节点性能的影响。结果表明,外联式矩管柱与H形钢梁节点具有良好的耗能能力和延性,节点的塑性耗能区集中在梁上,梁翼缘和腹板壁厚对节点的初始刚度、屈服荷载和极限荷载的影响较为明显,柱壁厚对节点力学性能影响较小。

Abstract

Low-cyclic loading experiments on a new type vertical outside connection between H-section beam and rectangular tube column were conducted. The damage phenomena and failure mechanism, the hysteretic performance and ultimate bearing capacity were presented. The software ABAQUS was adopted to establish the models in tests and the numerical results are almost consistent with the experiment ones. At the same time, the effects of the flange and web thicknesses of the beam, and the thickness of the rectangular tube column on the mechanical behaviors of the steel connection were analyzed. The results show that the connection has a good capacity of energy dissipation and is of enough ductility. The plastic hinges mainly occur in the beam. The initial stiffness, yielding load and ultimate load are obviously affected by the flange and web thicknesses of the beam. The thickness of the column has negligible effect on the behavior of the connection.
