摘要
随着特高压电网的建设,双组合角钢构件在铁塔设计中已广泛应用。本文基于某输电塔真型试验,分析试验数据,对双组合角钢的双肢受力不均匀性、次弯矩影响及长细比修正等方面作了深入的分析研究,得出了双组合角钢铁塔设计计算中的一些建议。
Double angles member have widespread applied in tower design with the development of UHV power grid. According to full-scale model test data report, we analysing the bearing capacity of double angles member which including non-uniform stress, subsidiary moment load, and slenderness ratio. The suggestion is applicable to the reinforcing design of double angles tower.
