| 摘 要： | 考虑钢管混凝土柱在轴向荷载作用下，研究钢管与混凝土柱芯间的相互作用，导出了两者之间的紧箍力以及柱芯受荷与钢管径向位移的计算公式并进行了实例计算，结果表明：紧箍力与材料的弹性常量有关，与所受荷载成正比；钢管的径向位移与荷载成正比；钢管混凝土柱的截面越小，紧箍力所起的作用越大，钢管径向位移也越大．

| Abstract: | The article analyzes the interaction between the steel tube and the concrete core of the Concrete-Filled Tubular Steel(CFTS) column when loaded from the axis,and worked out the formulas of tightening-ring force between the two sides,and the formulas of the load applied to the column core and the radial displacement of the steel tube.Sample calculation is conducted.The conclusion indicates: tightening-ring force is related to elastic constant of the material,and keeps direct ratio with the load.The radial displacement of the steel tube keeps direct ratio with the load.Heavier tightening-ring force and smaller CFTS column section results in bigger radial displacement of the steel tube. |

| Keywords: | CFTS columns column core stress displacement tightening-ring force |
