摘　　要：针对配有双圆钢管的钢骨混凝土柱的轴心受压承载力分析方法进行了研究,基于核心区混凝土、外围混凝土和钢管、钢筋的材料本构关系,建立了钢骨混凝土柱的有限元分析模型,分析了轴心受压承载力的计算方法及原理,对已有的承载力计算公式进行了改进,并通过工程实例的计算结果与有限元分析结果的对比进行了验证。Carrying capacity of steel reinforced concrete columns with double circular steel tubes under axial loading was studied. Based on the stress-strain relationships of the core concrete, the external concrete and steel tube, steel materials, a steel reinforced concrete columns FEM analysis model was established. The calculating method and principle of the axial compression capacity were analysed, then the existing formula was improved for steel reinforced concrete columns. The validation of equations were carried by comparing with the results of the FEM analysis for actual project.
