以ANSYS有限元分析软件为工具,建立了直接焊接式节点、外加强环板式节点、贯穿钢筋式节点模型,并在此三种基本模型的基础上改变节点相关参数,纵向分析得出每种节点在参数的变化与节点承载力变化的对应关系,横向分析得出此三种节点模型的承载力及延性的对比结果。从计算的结果的M-θ曲线中可看出贯穿钢筋式节点延性及承载力均优于直接焊接式节点和外加强环式节点。 ANSYS finite element analysis software as a tool to establish a direct welding node, plus a strong ring plate node, throughout the reinforced node model, and based on these three basic models to change the parameters of the node, the longitudinal analysis of each node In the corresponding relationship between the change of parameters and the change of node bearing capacity, the comparison results of bearing capacity and ductility of these three joint models are obtained through horizontal analysis. From the M-θ curve of the calculated results, it can be seen that the ductility and the bearing capacity of the through-reinforced joints are better than those of the direct welded joints and the extra strong annular joints.
