| 摘 要： | 根据正交试验理论,设计了不同混凝土强度、钢管强度、钢管厚度、长细比等的钢管混凝土试件,通过轴心受压加载方式测试其承载能力.试验结果表明:受轴压载荷时,钢管混凝土的强度随着混凝土强度、钢材强度、钢管厚度的增加而增加,随着钢管混凝土的高度增加而减小.

| Abstract: | To test its bearing capacity,the different concrete strength,steel pipe,steel pipe thickness strength and slenderness ratio of concrete filled steel tube were designed with the theory of the orthogonal.The results showed that: when subject to axial compression load,the CFST strength increased with the concrete strength,steel pipe,steel pipe thickness strength increases,and reduced with the increase of the height of CFST. |

| Keywords: | elliptical cross section CFST orthogonal |
