摘　　要：针对采用缀板连接形式的方钢管混凝土柱-工字型钢梁节点的力学性能,利用ANSYS有限元分析软件进行了三维有限元模拟数值模拟,有限元计算结果与试验实测数据吻合较好。在此基础上,对若干影响节点受力性能的几何参数和材料参数进行了参数分析。结果表明,所建立的三维有限元数值分析模型是合理的,加劲肋的设置及缀板厚度等参数对节点受力性能的影响较为显著,而钢管混凝土柱的轴压比与钢管宽厚比等参数对节点的力学性能影响较小。In this paper,3D nonlinear finite element models are established to analyze mechanical behaviour of I-section steel beam to concrete-filled square steel tubular column joint with side-plate welding by finite element method ANSYS.The simulation results are in good agreement with experimental data.On this basis,parametric analyses are conducted to analyze the influences of several geometric and material parameters on mechanical behaviour of the joint.It shows that the nonlinear finite element models can be rationally established,stiffeness and side-plate thickness are important to the joint,and axial compression ratio and width-thickness ratio of steel tube work less.
