摘要:
提出了一种新型双T型钢 - 穿芯螺栓连接的方钢管混凝土柱 - 钢梁节点.该节点具有易于装配,震后可更换的特点.采用有限元分析软件ABAQUS建立足尺有限元分析模型,进行低周往复荷载作用下的精细化数值模拟,研究了T型钢翼缘、腹板以及抗剪板的厚度对该节点滞回性能的影响.结果表明:新型双T型钢 - 穿芯螺栓连接的方钢管混凝土柱 - 钢梁节点具有良好的强度、刚度和耗能能力.T型钢翼缘厚度对节点承载力影响较大,对节点初始刚度和耗能能力的影响较小.T型钢腹板厚度对节点承载力、节点刚度及耗能能力均有较大影响,增大腹板厚度可提高节点的承载力和初始刚度,梁端转角达到0.035后,增加腹板厚度可提高节点的耗能能力.抗剪板厚度在该节点的设计中不起控制作用.
Abstract:
This paper proposed a new type of steel beam to concrete-filled square steel tubular column joint which is connected with double T-stub-bidirectional bolts. This kind of connection is an easy assembled and replaceable joint. Full-scale finite element analysis model was established by using the nonlinear finite element software ABAQUS, and the numerical simulation analysis under low cycle loading was carried out, so as study the influence of the different thickness of T-stub steel flange, web and shear plate on the hysteretic behavior of this joint. Results show that the steel beam to concrete-filled square steel tubular column joint with double T-stub-bidirectional bolts has good strength, stiffness and energy dissipation behavior. The thickness of T-stub steel flange has great influence on the bearing capacity of the joint but limited influence on stiffness and enegy dissipation. The thickness of the T-stub steel web has a great influence on the strength, stiffness and energy dissipation of joint. The thickness of the shear plate has little effect on hysteretic behavior of joint.
