摘　　要：针对钢筋混凝土轴心受压构件的正截面承载力这一问题,将中美相关规范进行了对比,并通过算例进行了具体的比较。结果表明,对于相同轴压构件,美国规范计算得到的纵筋配筋面积大于中国规范的要求,并且这一差异随着短柱长细比的增大而减小。The relevant design codes of China and America are compared for the axial load bearing capacity of reinforced concrete columns, and the differences are elaborated by a calculation example. The result shows that for the same axial compression members, the reinforcement area calculated by American code is larger than that calculated by Chinese code. The difference decreases with the increase of the slenderness ratio of the column.
