| 摘 要： | 从钢骨-钢管混凝土组合柱的工作机理出发,分析了其各组成部分应力状态,提出了计算钢骨-钢管混凝土轴压短柱的简化模型。根据组合柱各组成部分极限(屈服)条件,应用极限平衡理论建立了截面的力学平衡方程,基于钢骨翼缘对核心混凝土的附加约束,推导了该组合柱的轴压极限承载力计算公式。计算结果表明,有关实验值与本文理论计算结果较吻合。

| Abstract: | The stress state of a composite column and a short steel tubular column filled with steel-reinforced concrete was comprehensively analyzed and rationally simplified.Based on the mechanical behavior of the composite column and the yield condition of its components,a formula for computing the ultimate bearing capacity was obtained with the limit equilibrium method.The calculated results of the proposed formula agree with the experimental ones reported in other papers. |
