摘　　要：目的分析钢管混凝土组合柱研究中的不足,提出了钢管-钢骨混凝土组合柱的概念,研究钢管-钢骨混凝土组合柱的破坏机理、受力性能.方法对钢管-钢骨混凝土组合柱的破坏机理、受力性能,进行了3个含钢率不同的偏心受压钢管-钢骨混凝土短柱的试验.结果钢管混凝土柱存在内外部分破坏不同步的可能,通过试验,明确了钢管-钢骨混凝土柱的破坏特征,含钢率对承载力的影响,含钢率越大,构件的承载力及延性的相应增加.结论试验结果表明,当含钢率大于0.36%时,钢管混凝土柱与其外测的钢骨混凝土能够共同工作直至破坏,其承载力明显高于钢管混凝土核心柱的承载力,为组合结构的发展提供了一种新的结构型式.For solving the problem in the study of circular steel tube compile column filled with reinforced concrete, an innovative column of circular steel tube composite short co!umn filled with steel reinforced concrete has been brought forward by the principle of concept design. In order to master the damage and capacity of circular steel tube composite short column filled with steel reinforced concrete, the experimental study has been done under eccentricity load of circular steel tube composite short column filled with steel reinforced concrete that has three type steel ratios. Through the experiment, we can know the damage character of circular steel tube composite short column filled with steel reinforced concrete and the effect of carrying capacity and ductility under steel ratio. Finally, circular steel tube concrete column and steel reinforced concrete can work together well to damage. A new structure type has been suggested for the development of composite structure.
