摘　　要：目的提出钢骨-钢管混凝土组合柱的概念,消除钢骨混凝土组合柱内外部分不能够同时破坏的可能.方法应用有限元的方法,对含钢率不同的轴心受压钢管-钢骨混凝土短柱进行了模拟研究,并与实验情况进行比较.结果明确了钢管-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也会相应的增加.结论钢骨-钢管混凝土组合柱具有很大的优势,能够克服钢管混凝土组合柱的不足.模拟计算与实验研究结果吻合较好.Because of the column of circular steel tube filled with reinforced concrete,a new column has been brought forward,which is circular steel tube composite short column filled in steel reinforced concrete.To research into damage and capability,the simulate test has been made,and the results proves to be preferable.The study indicates that the steel ratio has an evident effect on the ductility and the capability：the bigger the steel ratio is,the larger the ductility and the capability are,and the circular steel tube composite short column filled in steel reinforced concrete has a prodigious prospect in engineering practice.
