摘　　要：内蒙古呼和浩特轨道交通大型换乘站1号线、中山路站2号线,梁柱节点设计采用双梁-双暗牛腿的形式。文章采用ABAQUS有限元数值模拟的手段,针对该种节点的抗剪性能开展系统的研究,并与检测的数据进行对比。通过研究得到以下结论:下部牛腿的剪力约为上部牛腿的2倍,破坏时梁上表面与钢管接触位置应变较大。For line 2,Zhongshan Road Station,Line 1,a large transfer station in Hohhot,Inner Mongolia,the beam-column joints are designed in the form of double beams and double dark legs In this paper,ABAQUS finite element numerical simulation method is adopted to carry out systematic research on the shear performance of this node,and compare with the tested data.The shear force of the lower leg is about 2 times as much as that of the upper leg,and the strain at the contact position between the upper surface of the beam and the steel tube is larger when the upper leg is damaged.
