摘　　要：以2个空间剖分T型钢梁柱连接角柱节点模型、1个刚性连接角柱节点模型以及2个平面剖分T型钢节点模型为研究对象,完成剖分T型钢梁柱连接模型的拟静力试验.得到各节点模型的承载能力、应变发展状况、破坏形式、滞回性能和耗能特性;分析弱轴对强轴的影响程度;探讨空间剖分T型钢梁柱连接节点与平面剖分T型钢梁柱连接节点受力性能的差异.研究结果表明:在低周反复荷载作用下,钢框架角柱节点空间效应明显,不能忽略弱轴对强轴的影响,还应考虑空间影响因素.Quasi-static experiment was taken for beam to column joint models which connected by T-stubs with taking the following models as research objects：two beam to column spatial corner joints models connected with T-stubs,a beam-column spatial rigid corner joint model,and two beam to column plane joints models connected with T-stubs.Bearing capacity,strain development,failure mode,hysteretic performance and energy dissipation of each joint were obtained;the influence of the minor axis on the major axis was analyzed;the difference of the mechanical properties between the spatial joints and plane joints which connected by T-stub were investigated.Results show that under low cyclic loading,the spatial effect of the corner column joints is obvious and the effect of the minor axis on the major axis can not be neglected,while the spatial influence factors should be taken into account.
