A325 bolts in lieu of A394
A325 bolts in lieu of A394
(OP)
Specs says we have to use A394 bolts for transmission towers.
But we want to propose to use A325 instead. Will there be any effects on the tower if we use A325 instead of A394 bolts?
thanks in advance.

Look up the mode of testing failures in the history of the tower types before you go changing bolts.
By the way, do you know that a lot of towers test between 1.01 and 1.15 times the full design load and fail?

A few tubular poles use sloppy connections with oversize holes, such as 1 1/2" studs in 1 3/4" holes where the fastener does not really clamp the pieces together. (The concept is to confuse the linearity of the frequency responce to destruction by VonKarman vortices.)
Iouone2, are you looking at the thread you have started? Do you have the information you requested? If you need to talk to some people in the design end of things, let me know.
