摘 要:为了实现钢框架“强柱弱梁,强节点弱构件”的抗震设计目标和推广梁翼缘扩翼式连接在H形柱钢框架设计中的应用,本文通过参照梁与箱型截面强轴连接时的扩翼参数,设计了梁柱弱轴连接的扩翼型节点系列试件,应用有限元软件ABAQUS分析研究了扩翼区的外伸宽度bwf对扩翼型节点滞回性能的影响。通过有限元分析,得出结论:扩翼区的外伸宽度对节点的骨架曲线影响较大。In order to realize the seismic design goal of steel frame “strong column weak beam,strong joint weak member” and promote the application of beam flange expansion wing type in the design of H-shaped column steel frame,In this paper,the series of flared joints of beam-column weak-axis joints are designed by referring to the wing-expanding parameters when the beam is connected with the strong section of the box section,The finite element software ABAQUS is used to analyze the influence of the overhang width bwf of the flared region on the hysteretic behavior of the expanded wing node.Through the finite element analysis,the overhanging width of the expanding wing region has a great influence on the skeleton curve of the joint.
