摘要: 将复式钢管砼空心柱分成核心砼、内钢管和外钢管3部分,通过对核心砼进行轴对称柱体分析和钢管的薄壳 分析,考虑核心砼和内、外钢管的径向位移和纵向应变的协调条件,建立了复式钢管砼空心柱抗压刚度EA的计算 公式.同时分析了内钢管泊松比、外钢管泊松比、核心砼泊松比对构件抗压刚度、钢管与核心砼应力比的影响,得出 了一些有益的结论

关键词: 复式钢管砼, 抗压刚度, 弹性分析

Abstract: Composite concrete-filled steel tube is divided into three parts of core concrete, inner steel tube and outer steel tube. Core concrete is analyzed by using elastic axisymmetric pillar and steel tube by using thin shell. Based on the compatibility of radial displacement and longitudinal strain, the compressive stiffness of CCFST is derived. The influence of inner steel tubular Poisson’s ratio?outer steel tubular Poisson’s ratio and concrete Poisson’s ratio on compressive stiffness and stress rat

Key words: composite concrete-filled steel tube, compressive stiffness, elastic analysis
