摘　　要：本文首先分析了水平荷载作用下叠合柱的轴力在混凝土和钢骨之间的分配关系及有关参数对其分配关系的影响，讨论了组合构件轴压比的概念 ,在此基础上通过理论推导和数值计算两种途径给出了钢骨高强混凝土叠合柱名义轴压比限值的计算公式，该公式与现行规范吻合，可直接应用于工程设计。The redistribution of the axial force between concrete and reinforcement of steel reinforced high strength concrete compound column and the influences of compound ratio, axial compression ratio, strength of concrete, ratio of the area of steel to the area of the column on the redistribution have been analyzed with the concept of axial compression ratio of such column discussed. Based on theoretic and numerical studies, the formulas for computing axial compression ratio limit values of steel reinforced high strength concrete compound column are derived. The presented formulas are in accordance with the current design code.
