| 摘 要： | 铝合金轴心受压构件需要引入系数ηas来考虑截面不对称性带来的不利影响。在大量数值分析的基础上，提出了系数ηas的计算公式，可以作为设计计算的依据。提出了广义的稳定计算系数的概念，用以在确定铝合金轴心受压构件的屈曲抵抗力时考虑系数田．的影响，这样可与惯用设计方法相一致。

| Abstract: | Coefficient ηas was introduced to determine the adverse effect of the asymmetrical crosssection on aluminium columns. Based on a large number of numerical calculation results, a formula for resolving ηas that can be used for engineering design calculation was presented. General calculation coefficient was proposed to determine the buckling resistance of aluminium columns involving the effect of ηas, which accorded with common design method. |
