摘要
将钢管混凝土分成混凝土和钢管两部分,通过对混凝土进行轴对称柱体分析和钢管的薄壳分析,考虑钢管和混凝土径向位移、纵向应变协调,建立了钢管混凝土结构抗压刚度EA的计算公式,并与试验结果及其他计算方法进行比较,同时分析了钢管和混凝土的泊松比对钢管混凝土抗压刚度的影响。
Concrete-filled steel tube is considered into two parts of steel tube and concrete, concrete is analyzed by using 3D axisymmetric pillar and steel tube by using thin shell. Based on the compatibility of radial displacement and longitudinal strain, the compressive stiffness of CFST is derived. This method is compared with other experimental data. The coefficients of concrete Poisson's ratio and steel tube Poisson's ratio are also analyzed.
