摘　　要：为研究钢骨-钢管混凝土组合柱的抗弯性能,采用有限元软件ABAQUS数值计算方法分析不同的钢管强度、钢骨强度、钢管厚度、钢骨截面惯性矩和混凝土强度等级对钢骨-钢管混凝土组合柱的抗弯力学性能的影响.研究结果表明:数值计算结果与试验结果吻合良好;钢管强度、钢管厚度、型钢的截面惯性矩及混凝土强度等级对其抗弯力学性能均有影响,但影响程度不同.In order to study on the flexural performance of steel tubular columns filled with steel-reinforced concrete, this paper analyzed the composite columns influenced by different steel tube strength, different inserted steel strength, different thickness of steel tube, different steel cross sectional moment of inertia and concrete strength influence by using finite element software ABAQUS. The results indicate that a good fit is obtained between calculated results and experimental ones. The above parameters have an impact on the flexural mechanical properties with different degree of influence. The conclusion has a practical engineering significance on improving the flexural performance of composite columns through the rational utilization of materials.
