| 摘 要： | 以通用设计中的110 kV输电塔为计算模型，研究了将玻璃钢材料应用于输电塔上能满足结构稳定性的构件布置形式，采用特征值屈曲分析对风荷载作用下不同塔腿和塔身形式的输电塔进行了有限元计算。结果表明，主材用角钢、其他构件用玻璃钢的输电塔结构和改变塔腿形式或再进一步将塔身下半部改为具有水平材的双腹杆形式均能满足结构稳定性要求。

| Abstract: | According to the 110 kV power transmission towers in general design, the stable form of transmission tower used FRP components was researched. Considering the influences of the different arrangement of tower legs and tower body on the stability of structure, the finite element calculation of transmission tower under wind load was carried out through the eigenvalue buckling analysis. It is concluded that the transmission tower whose principal material are angle steel and others are FRP can meet the requirements of the structure stability through modifying the form of legs or the first body to become the double ventral pole form with a level pole. |
