摘　　要：基于ABAQUS有限元软件,对空鼓下的内隔板式钢管混凝土柱-H型钢梁边跨节点进行数值分析获得试件的荷载-位移滞回曲线,通过与试验结果对比,二者吻合较好,验证了部件之间相互约束、接触作用、材料本构关系等设定的精确性和合理性。且又进一步模拟分析了空鼓占比大小及位置、内隔板厚等参数对存在空鼓的试件节点承载能力与抗震性能的影响规律,结果表明随着空鼓占比大小以及内隔板厚的增加,节点极限承载力会逐渐降低,此外钢管混凝土梁柱节点连接处的焊缝质量,对试件节点的抗震性能有较大的影响,通过上述模拟分析,为今后该类节点在实际工程中的应用提供了理论依据。Using ABAQUS software,the side-span joints of an inner bulkhead-type concrete-filled steel tube column-H steel beam under a hollow drum are simulated,and the simulation data are compared with experimental data.The results show that the software simulation skeleton and hysteresis curves are consistent with the test results;The accuracy of setting the mutual constraints,contact effects,and constitutive relationships of materials between components are further verified.In addition,the factors such as the size and position of the hollow drum and the thickness of the inner bulkhead are further simulated and analyzed,which affect the bearing capacity and seismic performance of the joints of the test specimens with the hollow drum.Through the above simulation analysis,it provides a theoretical basis for the future application of this kind of nodes in practical engineering.
