摘要
提出一种新型穿心高强螺栓-端板方钢管混凝土柱-钢梁节点,并对3个节点试件进行柱端加载的伪静力试验研究。利用三维实体单元,建立同时考虑几何、材料及接触等三重非线性的有限元模型,采用有限元程序ANSYS对节点进行单调荷载和循环荷载作用下的有限元分析。试验及有限元计算结果表明,节点具有很好的强度、刚度、延性和耗能能力。
A new type of through high strength bolts-end plate connection for concrete filled square steel tube column and steel beams is proposed. A total of 3 pseudo-static experiments has been conducted in which the horizontal cyclic load is applied on the top of the column. The nonlinear finite element models involving geometric, material and contact nonlinearities are presented using 3D solid elements. The ANSYS finite element package is used to simulate the nonlinear behavior of the experimental specimens under the monotone and cyclic loading. The results obtained from the finite element and the experiments show that the connections have excellent strength, stiffness, ductility and energy dissipation capacity.
