摘　　要：Q460钢材在输电线路铁塔中的使用越来越多,但是现行规范中没有关于Q460钢材的规定,相关的参数无资料可查,使Q460钢材的应用缺少依据。采用逆算单元长度法编程计算了63种不同规格的Q460等边角钢的柱子曲线,并统计出了Q460等边角钢轴压构件的稳定系数表,与试验及有限元分析的对比表明,该柱子曲线是合理的,可用于Q460等边角钢的设计。The application of Q460 equal angle steel in transmission towers is more and more popular, however in current codes there are not regulaions related to Q460 equal angle steel, so that the paramters of Q460 equal angle steel are not listed in related references and it makes the application of Q460 equal angle steel lacking of basis. In this paper, the inverse calculation segment length method is applied in the programming to calculate column curves of 63 kinds of Q460 equal angle steel, and based on statistic results a coefficient table of stabiltiy of axle loaded member made of Q460 equal angle steel is obtained. Comparison results of the contents in the obtained table with the test results and the calculation results by ANSYS software shows that the obtianed column curves are rational and can be applied in the design in which the Q460 equal angle steel is adopted.
