Eye-Bolt Through Channel Web
Eye-Bolt Through Channel Web
(OP)
Hi,
I am not sure what the technical term is, but I am curious if anyone has experience with bolting an eye-bolt through the web of a channel.
We are trying to find a tie off point for someone which needs to be rated for 5,000 lbs. We have since decided on a different option, but one of the ideas discussed was to drill through the web of a channel and install an eye-bolt for a tie off. I'm curious what the structural checks would be in this situation? Web bearing due to the bolt? Any local bending or crippling?
Is practice common?
Thank you!

Eye bolts should always be loaded axially, in anything other than a last-resort situation.

We would not use an eye-bolt the way you describe. We have previously provided a piece of plate welded to the supporting steel with an opening for the tie-offs.

I've seen something similar. Typically in a prefab metal building. (Except that it would be bracing for lateral loads, it would be going into wide flange columns, and it wasn't a eye-bolt at the end (just nuts).)
Definitely localized bending in the web (not to mention shear) would be very important checks. And with an eye-bolt.....if I didn't have a nut in front of it (in contact with the web)....I'd minimize the contact area by which the force was being applied. If not, you could initiate deformation in the web as it tried to pull through.
Also (as the others have said) you typically don't see an eye-bolt used for this (in bending). I'd just use nuts at the end of a threaded rod. (And into a flange would be better.)
