摘要:
针对钢管混凝土束剪力墙结构提出了2种全螺栓刚性连接节点,共设计了6个基于高强螺栓的钢管混凝土束剪力墙-H型钢梁全螺栓端板式连接节点和1个钢管混凝土束剪力墙-H型钢梁全螺栓侧板式连接节点。对7个节点进行了低周往复加载试验,采用ABAQUS软件建立有限元模型,将有限元模拟结果与试验结果进行对比验证后,通过参数化分析系统研究了不同参数对钢管混凝土束剪力墙-H型钢梁全螺栓连接节点抗震性能的影响。结果表明:2种全螺栓连接节点均能实现刚性连接; 端板式节点的刚度主要取决于钢梁端板厚度和墙体端板厚度,侧板式节点主要通过螺栓的滑移来耗散能量,表现出低屈服承载力、高延性的特点; 侧板式节点中螺栓直径、摩擦因数对节点滑移荷载有较大影响,对抗弯极限承载力影响较小; 给出的节点设计建议可为工程设计提供参考。
Abstract:
Two kinds of all-bolted rigid connection joints were proposed for concrete-filled multicellular steel tube shear wall. A total of six concrete-filled multicellular steel tube shear wall-H-shaped steel beam all-bolted end plate connection joints based on high strength bolts and one concrete-filled multicellular steel tube shear wall-H-shaped steel beam all-bolted side plate connection joint were designed. The cyclic loading test of seven specimen joints was conducted. The finite element model was established by ABAQUS software. After comparing the finite element simulation results with the experimental results, the influence of different parameters on the seismic behavior of concrete-filled multicellular steel tube shear wall-H-shaped steel beam all-bolted connection joints was studied by parametric analysis system. The results show that the two all-bolted connection joints can achieve rigid connection. The stiffness of end plate joints depends mainly on steel beam end plate and wall end plate thicknesses. Side plate joints dissipate energy mainly through the slip of bolts, showing the characteristics of low yield-bearing capacity and high ductility. The bolt diameter and friction coefficient in the side plate joints have a great influence on the sliding load of the joints, and the influence on the bending ultimate bearing capacity is small. The proposed design suggestions for joints can provide reference for engineering design.
