摘　　要：文中借助有限元软件ABAQUS对往复加载下4个钢管混凝土柱—钢梁节点进行了有限元分析,结果表明:有限元模型计算获得的的试件破坏形态、刚度退化、峰值承载力、滞回环面积均基本符合实验结果,计算的峰值承载力、最外圈滞回环面积与试验相对误差在20%以内,证明了模型的有效性,为组合结构节点研究提高参考。With the help of finite element software ABAQUS, this paper carries out finite element analysis on four CFST column-to-steel beam joints under cyclic loading. Results show that the finite element model of the specimen failure pattern, stiffness degradation, peak capacity, hysteresis loop back on the test results conform to the area is good, the relative error between the calculated peak bearing capacity and the area of the outermost ring hysteresis ring and the test is less than 20%, which proves the validity of the model and provides a reference for the study of composite structure joints.
