[TowerTalk] Achor bolts?

[Steve Jones]

Hans-

My 89' US Tower crankup has 2 anchor bolts at each leg, a total of 6 bolts.
Each bolt is 1 -1/8" diameter and 27" long of ASTM grade 36 steel.

I think I'd trust US Tower's licensed PE wet-stamped drawing before
Facebook!

Dear towertalkers,

The are claims in a discussion on Face Book that an anchor bolt, "5/8 in. x
12 in. Hot-Galvanized", is suitable for a free standing tower. Someone even
claims it is used for a 400' freestanding tower. It doesn't make sense to me
but I might be overly pessimistic.

I hate to start lengthy discussions and this might be one of them so,
please, comment only if you have a well grounded answer. I'm sure there are
plenty of opinions about it like my own, but I would like to know if my guts
feeling is right or wrong. What I am afraid of is that you can pull out an
anchor bolt like that right out of curred concrete.

73 de,

Hans - N2JFS
