摘要
超高大跨越输电铁塔设计中, 组合构件一般使用斜缀条连接的四肢组合构件。因此, 主要讲述该构件的设计计算方法, 对使用自立式铁塔内力分析(TTA)程序准确计算组合角钢长细比和缀条的方法作了较深入的探讨, 并在此基础上, 对存在的问题提出了解决办法。
The four-limb combined member connected with lacing bars is generally used in the design of superhigh crossing transmission towers.This paper deals with the design and calculation method of this member,and researches the means of accurately calculating the slenderness ratio of assembly angle iron and the lacing bars with the TTA program for internal force analysis of self-supporting towers.On the basis of that,solutions to the existing problems are put forward.
