摘要(Abstract):

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。
Using ANSYS finite element analysis software,there models,the directly welded joints,joints with exterior strength ring and joints impenetrated by reinforcements are built to analysis the characteristics of the rigid joint.With changing the parameters of the basic joints models and comparing longitudinally,the article concluded the corresponding relation between every parameter and capacity,with comparing horizontally,the article concluded the capacity and ductility's relation of the three kinds of joints.Form the M-8 diagram,the capacity and ductility of joints impenetrated by reinforcements have the advantage over the directly welded joints,joints with exterior strength ring.
