Guy tensions

Guy tensions

300' all weld tower. (question),
spec tension for 7/16" galv. guy strand.
temp.20 degrees celsius

RE: Guy tensions

The initial tension for guy wires for guyed towers is normally 10 percent of the breaking load of the tendon, with upper and lower limits of 15% and 8%.  This is based on the TIA/EIA-222-F "Structural Standards for Steel Antenna Towers and Antenna Supporting Structures".  Assuming that your 7/16 in. guy is EHS 7-wire strand (extra high strength), the breaking load would be 20,800 lbs, so the preload would be 2080 lbs.

RE: Guy tensions

Could someone explain the acronym TIA/EIA-222-F "Structural Standards for Steel Antenna Towers and Antenna Supporting Structures" and where I can obtain a copy.  It is not available from Amazon.com.  I am interested in their calculation of guy tension using a tangential line of sight from the base of the guy to the mast.

TIA - Telecommunications Industry Association
EIA - Electronic Industries Associations

The document should be available from IHS Global
