摘　　要：本文通过对 3种长度的方形钢管混凝土柱和 2种长度的矩形钢管混凝土柱的试验分析 ,比较了 2种计算柱子轴压稳定系数的方法 ,得出了现行公式能很好地计算方形钢管混凝土柱的轴压稳定系数 ,但对于矩形钢管混凝土柱的轴压稳定系数计算 ,还必须进一步修正。Experiment is carried out on three kinds of steel hollow square columns filled with plain concrete and two kinds of steel hollow rectangler columns filled with plain concrete in length under axial load.Through calculating the stability coefficient of columns in two different ways,this paper conducts that the experiment is coincide with the formula on steel hollow square columns filled with plain concrete,which can't be used to calculate the stability coefficient on the steel hollow rectangler columns filled with plain concrete and need to be revised.

关 键 词：矩形 钢管混凝土柱 稳定系数 轴心
