摘要:
利用有限元软件ABAQUS对方钢管再生混凝土短柱轴压承载力进行非线性分析，建立了适用于有限元分析的钢管和再生混凝土本构关系模型；利用极限平衡法推导方钢管再生混凝土短柱轴压承载力计算公式函数类型；利用计算结果拟合出方钢管再生混凝土短柱轴压承载力的计算公式。研究结果表明：所提出的材料本构关系模型可以较好地满足对方钢管再生混凝土短柱轴压承载力进行模拟分析的要求，通过模拟获得的计算结果与相关试验结果差异较小，所建立的方钢管再生混凝土短柱轴压承载力计算公式能够较准确地计算构件极限承载力。
Abstract:
Nonlinear analysis of bearing capacity for recycled concretefilled square steel tubular stub columns under axial compression was carried out using finite element software ABAQUS. The authors put forward the modified model of the constitutive relationship of steel and recycled concrete, and deduced the function relation of ultimate bearing capacity formula of concretefilled square steel tubular stub columns under axial compression by using ultimate equilibrium method. The finite element calculation results were used to fit the ultimate bearing capacity formulae of recycled concretefilled square steel tubular stub columns. The study results indicate that the modified formulae of recycled concrete constitutive relationship can meet the requirements of regeneration stub columns under axial bearing capacity well. There are small differences between finite element calculation results and related test results. The established calculation formulae of bearing capacity for recycled concretefilled square steel tubular stub columns under axial compression can calculate the ultimate bearing capacity of members accurately.
