| 摘 要： | 盖板加强式梁柱刚性连接节点是使塑性铰外移以提高节点塑性变形的一种改进形式。采用通用有限元软件ABAQUS,对梁柱盖板连接在单调荷载作用下的受力性能进行了三维非线性有限元分析。分别考虑柱腹板厚度、柱翼缘厚度及柱翼缘宽度的影响,设计了3组共12个试件,总结了这3个因素对节点承载力和刚度的影响,为此类节点的设计提供了参考。

| Abstract: | Cover plate(CP) reinforced steel moment resistant frame(MRF) connection is one of improved forms to move plastic hinge outward from the beam and column interface.By using ABAQUS software package,this paper has done the 3-D nonlinear finite element analysis on the performance of cover plate connection under monotonic load.This paper presents analysis data on 12 specimens that consider the effects of beam web thickness,beam flange thickness and beam flange width.By summarizing the effects on strength and stiffness of cover plate Connection due to these three factors,it provides the references for the further design of CP connection. |
