摘　　要：用ANSYS有限元程序对方钢管混凝土柱-钢梁穿芯螺栓端板半刚性节点的非线性性能进行了理论分析,并将计算结果与试验结果进行了比较,两者吻合较好。通过对6个系列共13个方钢管混凝土柱-钢梁穿芯螺栓端板连接试件的非线性有限元分析,重点探讨了连接的各类组件对节点力学性能的影响。结果表明:端板加劲肋和高强螺栓预应力对节点力学性能有较明显的影响,端板厚度和轴压比对节点力学性能有一定的影响,螺栓直径及排列间距对节点力学性能的影响较小。To analyze the nonlinear behaviors of through end-plate bolted semi-rigid connections for concrete filled square steel tubular column-steel beam theoretically by ANSYS finite element program and to compare the result with testing result,we find the two results are identical. Through analyzing 6 series of total 13 through endplate bolted connection samples by finite element and mainly discussing the effects of several of components connected to mechanical influence on mecchanical properties of the node. The result show that the stiffening plate of end plate has great influence on mechanical properties of the node;The thickness of the endplate and the axial load ratios have a certain influence on mechanical properties of the node ; the bolt diameter and spacing arrangement have less influence on mechanical properties of the node.
