Clay,
It's listed indirectly on the older Rohn tower drawings I have here. For
instance, on Dwg C-630625-R (for rohn 25), it tabulates:
"Wind Load per lineal foot of tower at the horizontal wind pressures
(per square foot of flat surface)
30 lbs - 7.62
40 lbs - 10.16
50 lbs - 12.70"
>From this, I conclude that Rohn considered 0.25 square ft/ft to be the
effective area of the R25.
