基于半刚性梁柱弱轴端板连接一般将端板与柱的腹板连接或者将端板焊接于柱的2个翼缘间，端板与柱腹板连接对柱的腹板有削弱作用，端板焊接在柱的2个翼缘之间会因为柱翼缘板厚的限制而不易施焊，因此，提出一种既容易焊接，又对柱的腹板没有削弱作用的连接：加槽钢作连接构件的半刚性弱轴端板连接。运用用有限元软件ABAQUS建立强轴弱轴共存的空间半刚性梁柱端板连接节点的非线性有限元模型，采用合理的材料本构关系，在试验验证的基础上，分析了强、弱轴在5种荷载工况作用下的转动特性，以模拟实际工程中角柱、边柱和中柱上强、弱轴节点的实际受力状态。研究结果表明：加槽钢作连接构件的弱轴端板连接避免了对柱腰板的削弱，具有良好的变形能力，属于典型的半刚性连接；强弱轴同时加载时节点的承载力基本一致，但节点的初始刚度有较大区别；本文提出的结点构造可为实际工程提供参考。

Generally,in semi-rigid beam-to-column connections of minor-axis,end plate is located in col-umn web or welded to the column between two flanges.When the end plate is located in column web,there will be a weakening effect on the column web.While welding to the column between two flanges,it will be difficult to weld due to the restrictions of column flange's thickness.In this paper,semi-rigid beam-to-column with channel component was proposed that not only has no weakening effect on the column web,but also is easy to weld.ABAQUS was used to establish the three -dimensional steel semi -rigid beam-to -column joints with channel component that consists of extended end -plats for both major and minor axis.Employing appropriate constitutive models and based on the experimental verification,the rotating characteristics of minor and major ax-is were discussed under 5 load cases in order to simulate the actual stress status of corner columns,side columns and interior columns.The study shows that the minor axis joint with channel has no weakening effect on the col-umn and good ductility,which belongs to a typical semi-rigid connection.The bearing capacities of nodes are almost the same but the initial stiffness is different when loading in both minor and major axis.The joint struc-tures proposed in this paper can give reference for the practical programs.
