Hi Steve
I have installed a few elevated guy anchor installations in the past. when
you say 8" flange length I assume your talking about the inner WEB length ?
Also not an engineer my installation are over kill for sure... one had a 12"
web 4" flange face 12 16 ft long. dug holes 9 to 10 ft deep the beams were
cut a a 45 deg angle at the top and drilled for 4 1/2" X 16 eye jaw turn
buckles. the bottom of the beams were drilled 3/4" holes for 6 rebar
lateral tie in, Used 1 1/2 yard 3000# mix in each hole with the beam place
not center but just off the front ( towards tower face ) The holes were back
filled ,
My installation is 150 ft of rohn 65 guys three ways and three levels with
about the same but each elevated posts were two bolted together 12" X 4" X 16'
U channel and the turn buckle bracket is a 8" X 6" T channel bolted to the
top of the exposed 6' U channels .
I have a set of PE drawings for 7' elevated guy posts somewhere in my file
cabinet. was for an installation of 150' rohn 55 in the New Mexico hardpan !
My personal opinion I do not like filling the hole to the top with cement...
when there is rain water seeping around the pour is becomes the wine bottle cork
and there is no mother EARTH resistance just the blocks weight just my
