摘　　要：对钢筋混凝土环梁节点进行了单调加载下的有限元分析,通过环梁节点试验结果与考虑混凝土损伤的非线性有限元分析结果的对比,验证了有限元分析的可行性,并介绍了钢筋混凝土环梁节点在ABAQUS中的建模过程。在此基础上,进行参数分析,研究了混凝土板、环梁箍筋、环梁与柱接触条件等因素对环梁节点受力性能的影响。FEM analysis on a ring beam joint in reinforced concrete structure under monotonic loading is completed, through the comparison between the test and the results of nonlinear analysis, feasibility of the FEM analysis is proved, and the modelling of the ring beam joint with ABAQUS is described. The effect of concrete slab,the stirrup in the ring beam and the contact condition between the ring beam and the column on the behavior of the ring beam joint is also examined.
