Guy Wire Safety Factor of 2.0

[Antnyt23]

In guyed tower analysis in accordance with TIA-222-G I see no reference to a safety factor of 2.0 for guyed wires, however, I have read and heard some places where this was common practice (not sure if maybe this was with previous standards). In TNX Tower the stress ratio for guys and wind when TIA 222-G is selected is locked at 1.0 so was just hoping to get a little clarification from the experts.

If you use the F standard, then you can set this to any value you want. For the G standard, I believe, the TnxTower program is using the G standard requirements directly and not allowing you to change it. Though I would guess that the program's output reports would more directly spell that out.

For previous versions of TIA, I believe the safety factor could vary based on a few different scenarios. That doesn't appear to be the case anymore with the G standard. Hence the reason why you cannot adjust it.
