角度风对转角塔水平荷载的影响

分析了转角杆塔设计时的荷载取值，将杆塔水平荷载分为水平风压荷载和水平张力荷载2种，考虑风对转角塔2侧电线的作用及对电线张力的影响，得出角度风作用下转角杆塔的综合水平荷载公式，并根据实际算例，探讨了杆塔最大水平荷载与大风角度的关系。结果表明，对于转角度数较大的转角杆塔，有必要根据实际情况计算角度风对水平荷载的影响。

Effect of Wind Angle on the Horizontal Load for Tension Tower

This paper analyzes loads on the tension steel tower for the tower design. The horizontal load on the tower is divided into horizontal wind load and horizontal tension load. Considering the wind pressure on the conductor at both sides of the tension tower and the tensile force of the conductor, the paper establishes a comprehensive formula for the horizontal load for the tension tower under the wind angle. Based on an actual example, the paper discusses the effects of the wind angle on the maximum comprehensive horizontal load. The result of the study shows that for those tension towers with large angles, it is necessary to calculate the angle of the wind on the horizontal load of tension towers based on the actual situation.
