摘要
对现有的钢管砼中核心砼的本构模型进行了数值分析;通过不同直径试件的轴压试验,分析了直径大小对模型的影响,得到了适合于大直径钢管砼的核心砼本构关系.
A constitutive relationship of core-concrete which suits to the big diameter concrete-filled steel tube was set forth through some widely applicable models as well as the methods of experiments and numerical analysis. The effects of diameter to model are given through axial compression experiments of different diameters samples.
