Does anyone have a reference for calculating worst-case guy wire tension
for a 3-wire system? The only thing I'm unsure of is the effect of wind
direction. One source states that worst case is for wind 30 degrees one
side of a guy, and is 1.15 times the force with the wind aligned with
the guy. The 1.15 factor is easy to calculate, but is that really the
worst case?. It's also clear that, with the wind exactly between two
guys, the tension in each is the same as when the wind is aligned with
one guy. Whether 30 degrees really is the worst case direction seems a
non-trivial calculation.
Note that I'm not asking about calculating the effect of vertical angle,
etc., as that's straight-forward. I'm just interested in the worst case
horizontal component of guy wire tension as a function of wind direction.
