摘　　要：在复杂钢结构组合节点的弹性分析和使用阶段的计算时,需要确定节点的初始转动刚度。为此,本文采用ABAQUS软件对12个试件展开了非线性有限元分析,获得了栓接节点梁在弯曲荷载作用下的破坏模式及转角-弯矩曲线。同时,基于材料力学和结构力学的基础理论,介绍了一种栓接H型钢梁柱十字半刚性节点初始转动刚度的计算方法,并与现有试验结果进行了对比。In the elastic analysis of the complex steel structure joint node and the calculation of the use phase,it is necessary to determine the initial rotational stiffness of the joint.To this end,this paper uses ABAQUS software to carry out nonlinear finite element analysis on twelve specimens,and obtains the failure mode and corner-moment curve of the bolted joint beam under bending load.At the same time,based on the basic theory of material mechanics and structural mechanics,the calculation method of the initial rotational stiffness of a half-rigid joint of a H-beam beam-column is introduced and compared with the existing test results.
