为了探索榫卯节点在钢-混凝土组合结构中应用的可行性,提出了一种钢混组合装配式节点——榫卯连接组合框架节点,设计并制作了2个足尺的榫卯连接节点,对其进行梁端单调静载试验,并采用ABAQUS软件进行有限元模拟分析,探讨了梁内钢筋面积的变化对节点破坏模式、承载能力、刚度、弯矩-转角关系等特征的影响。试验结果表明,该节点具有较好的承载能力和延性,梁内钢筋面积的增加使得节点的刚度、正弯矩区承载力有一定的提高,但对节点负弯矩区承载能力影响不大。节点的破坏模式主要为柱壁鼓曲变形、组合梁翼缘楼板受拉断裂。有限元模拟结果与试验结果吻合较好,验证了有限元模型的有效性。最后对该类节点...

In order to explore the feasibility to develop tenon-and-mortise joints in steel-concrete composite structures, a novel type of steel-concrete composite assembly joints, i.e., tenon-mortise joint composite frame joints was proposed. Two full-scale tenon-mortise joint node were designed and manufactured. The monotonic static loading test at the beam end was carried out, and the finite element simulation analysis was carried out using ABAQUS software, and the influence of steel bar amount in the beam on the failure mode, bearing capacity, stiffne...
