Welded-Welded Single Plate Shear Connections
Welded-Welded Single Plate Shear Connections
(OP)
I am working on a project where some of the floor beam connections have been installed incorrectly--single plate shear tab welded to BOTH the supporting girder and the supporting beam.
Of course, the contractor is asking me if this is acceptable--my first response was no, since there has been no testing on this type of connection (as far as I know), and it doesn't have enough ductility to be considered a "pinned" connection. I have been asked to look at the problem one more time.
Any ideas?

Thanks for the suggestion.
TehMightyEngineer,
Thanks also for your suggestions--in fact, they already installed bolts, but have not ground off the welds.
I went to a seminar a LONG time ago, where the presenter explained a single plate shear connection cannot transfer torsion into the supporting girder, because the end of the supported beam can only rotate a certain amount, resulting in a very small rotation of the supporting girder, and therefore little to no torsion. I think I will look into this.

Interesting, that would make some sense. Perhaps that's where I got partial moment connection in my head regarding my previous welded-welded single plate cnxn.
