摘　　要：钢管约束混凝土柱是在钢管混凝土柱、箍筋约束混凝土柱和型钢混凝土柱的基础上发展起来的一种新型组合结构构件,具有承载力高、延性好、抗火性能好、施工方便等优点。目前国内外对钢管约束混凝土柱的研究刚刚起步,以往的研究也主要集中在轴压短柱方面,而对工程中最为常见的中长柱构件鲜有报道。本文对圆钢管约束钢筋混凝土中长柱的轴压性能进行了有限元分析。通过有限元模拟,给出了圆钢管约束钢筋混凝土柱荷载位移曲线,并对其进行了全过程分析。A circular steel tubed reinforced concrete （CTRC）was a new type composite column, which was come from concrete filled steel tube column. CTRC has the advantages of high bearing capaci- ty, good ductility, good fire resistance and construction convenient. The research of CTRC just started for recent years in China, which was only focus on short column at previous study. The research of slender CTRC has not carry out, which was more common in engineering application. This paper presented a finite element simulation research on CTRC column. Load displacement curve under eccentric loading was given which match the experimental data well.
