在荷载等值线法的基础上，考虑均匀配筋形式，通过大量变参数、多水平的数值运算，拟合双偏压钢筋混凝土矩形柱截面轴压比与无量纲弯矩等值线的相关指数的函数关系，以及两主轴方向轴压比与无量纲参数m珟的关系曲线。基于所得强度曲线提出简化计算方法，并通过试验验证。给出算例以明确应用过程。提出的简化方法具有精度高、运算快的优点，可用于实际的工程设计。

Based on the load contour method , a series of section analysis of uniformly-reinforced rectangular RC columns were performed under the guidance of multi-factor and multi-level orthogonal parameter strategy . The polynomial relation between the exponent value of the dimensionless moment contour and the axial load ra -tio was statistically fitted .By introducing the dimensionless quantity m~in the principal axis direction , the vari-ation relation of moment capacity over axial load ratio was decoupled .A simplified design method was pro-posed and also verified with existing experiment data .Finally, the design procedure was illustrated through an example .The proposed simplified method is of high precision and computational efficiency , and applicable to engineering design .
