Abstract 为了研究相互作用下圆形钢管混凝土（circular concrete-filled steel tube，CCFST）柱中钢管和混凝土各自的承载力贡献，通过ABAQUS软件中的VUMAT子程序导入一种新的混凝土材料本构，建立了能够反映CCFST柱中钢管和混凝土相互作用的三维有限元模型，并通过试验数据验证了模型的荷载-位移曲线、钢管和混凝土的荷载-变形曲线以及侧向变形曲线。在此基础上分析了混凝土强度、钢管屈服强度、径厚比以及套箍系数对CCFST柱承载力及其组成的影响。然后结合有限元模型推导了CCFST柱在轴压荷载下峰值承载力的数学模型，模型中提出的钢管环向应力比例系数和混凝土承载力贡献系数可以评估钢管和混凝土的受力状态。将计算模型与现行规范及现有研究进行对比，发现提出的计算公式具有良好的计算精度，且可以评估钢管和混凝土各自的承载力贡献。
