the max wind load area for 70 mph rating of a free standing 55' Rohn 45
tower in 3 cu. yards of 1" rebar reinforced concrete (bottom section is 5'
in the concrete)? Or is it even possible to freestand that much 45?
It's not. You can get 2.3 square feet @ 45 feet for 70 MPH but that's
it. The factory free standing base spec calls for 4.1 cubic yards of concrete
so you come up short in both ends.
