计算输电塔受力时，若不考虑埃菲尔效应，可能导致计算值与实际受力不符。根据GB 50135—2006《高耸结构设计规范》中关于埃菲尔效应的计算公式和输电塔塔身的几何关系进行了推导，得出了可直接利用输电塔计算软件TTA结果文件的埃菲尔效应计算公式，并编写了输电塔埃菲尔效应的计算程序，可直接计算斜材内力和为选材提供参考。

If the Eiffel effect is not considered in mechanical analysis of transmission towers, the computed result may be different from their actual force conditions. Based on the Eiffel formula in 《Code for Design of High-rising Structures》（GB50135-2006） and the geometry of power transmission towers, an Eiffel effect formula is deduced that can directly make use of the results from transmission tower computation software TTA and a corresponding computation program is written for calculating the Eiffel effect that can calculate the force of the tower members and select member materials.
