摘　　要：利用大型有限元软件ABAQUS及有限元分析方法,应用钢筋混凝土框架节点的建模方法,研究了轴压比对节点抗震性能的影响。根据ABAQUS软件建立了试件模型,通过骨架曲线、耗能能力、滞回曲线等多个角度来研究低周反复循环加载对节点的抗震性能影响。轴压比越大钢筋混凝土框架节点抗震性能越好。In this paper,the large finite element software ABAQUS and the finite element analysis method are used.and the modeling method of the reinforced concrete frame node is discussed.the axial compression ratio on the seismic performance is mainly studied in this paper,the specimen model is established based on ABAQUS software,and the low reversed cyclic loading is established,its seismic performance of the node is studied by skeleton curves,energy dissipation capacity,hysteretic curves,from various angles.It is concluded that the larger the axial compression ratio,the better the seismic behavior of reinforced concrete frame node.
