Folded Plate Clip Connection
Folded Plate Clip Connection
(OP)
Hey Guys,
As we all know, in clip angle shear connection, the return weld 2t at the top allows the connection to rotate at ultimate load. But, if we are using the folded plate as a clip connection, is it fine to use 2t weld only at the top?
1. My intention says that I should use welded outstanding leg (not bolded - due to prying effect) at the supporting member and bolt it to the supported beam web
2. Removing 2t weld top instead should provide 3 sides weld at the outstanding leg to reduce prying effect
Apologies, if this may sound silly, looking for your greatest guidance

I get that in some jurisdictions angles are popular, but I don't see the benefit here over a simple welded cleat plate.
RE: Folded Plate Clip Connection
Practical notes:
1) I've almost never used angles welded to the support. It's impractical for erection because you'll need to do a lot of field welding or you can't swing your beams in.
2) You don't have a case where there is a true "prying action". That check comes with member axial loads. There is technically a small "prying" force from gravity loads and connection flexibility, but that is small and should be disregarded, unless you really want to dig into bending forces on your welds from a small horizontal offset.
3) Your skewed connection to the column web is impractical. At large skew angles, you are better served by another connection type, likely an extended shear plate or an end plate welded directly to the beam web (if the bolts can actually be installed).

In that case, is it fine to use the bolted-bolted clip connection?
As we know, the folded plate strength would never match the steel angle stiffness. So, I am afraid of the prying effect that will be much more than the steel angle.
And is it also fine to use 2t weld same as the angle for folded plates?
Thanks in advance!!

It can easily transfer shear force. But, if the beam has an axial force, no issues to use this, right?
Thanks in advance!!
