Horizontal Adjustment for steel to concrete Moment Connection
Horizontal Adjustment for steel to concrete Moment Connection
(OP)
Hey guys...
Im just wondering how could I provide horizontal adjustment for a steel beam (carries moment)to a concrete column without making slotted holes in the beam flange. Because as far as I know if the holes were slotted I should use S.C bolts which I cant.
Can anybody tell me what is the standard practice for such case.
The connection is:
A flange plate welded to the embedded plate and bolted to the beam flange (to carry the moment)
Shear plate welded to the embedded plate and bolted to the beam web with horizontal slots in the holes ( only carries shear).
Thanks in advance.

I think that's only true for slots parallel to load. You may be okay here.
If you're already welding the flange plate (to the embed plate), why not just weld it to the beam flange too? That would eliminate all kind of potential fit up issues.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Unless you mean lifting the beam with its connection (including the emb. PL)as one unit.? Is that achievable?
Thanks for replying kootk.

Are you not already site welding the flange plate to the embed plate? I don't see how you'd avoid that unless it's a precast column and the flange plate to embed weld would be made in the shop.
Consider posting a sketch. As far as I'm concerned, you're a rogue accountant right up until I see something on graph paper to convince me otherwise.
Happy to help Tristan.
