Tower Guy Load

October 1st Fact-of-the-Day

Load in tower guys depends on the guying arrangement used, the direction of the wind, the amplitudes of mechanical oscillations, and static guy tensions. There is a critical wind direction for any number of equally spaced guys that must be used to calculate maximum guy loads. Allowance should be made for wind loads on guys as well as on a tower, especially where a tower is tall. An additional allowance should be made for initial erection tensions which may be significantly higher because a tower is not yet perfectly straight and vertical or because static guy tensions have not yet be correctly set. Professional engineering practice generally is to use guys that can withstand 2.5 times the worst-case sum of all these loads. ©2004 Martek International All rights reserved.
