RE: Bent anchor bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bending back bolts is a bad practice, although possible in
some instances.
A 36 small bolt diameters if carefully preheated, and the column carries
no moment.
For high strength bolts it is a more difficult situation.  By bending back
bolts
the structural integrity is damaged, and they also may fail in  rupture.
Welding then may be required and that is completely a different issue.

I have a question that was asked of me and I could not locate a solid
answer anywhere.  I figure someone here will know...

Say you have an anchor bolt (opps, that would be anchor rods...damn, keep
forgetting that) sitting there out in the field prior to the column being
placed and it is just minding its own business, when "Wham!" someone runs
into it and bends it.  Someone asked if there is anything in a code
document that would prevent that anchor rod from being cold bent back
straight.  If there is nothing in code form, any personal opinions on cold
bending it back straight?

Thanks,
