Does this connection work?
(OP)
I'm reviewing a project and it has a framing detail similar to the attached sketch. This condition isn't really covered under any AISC design guide or typical detail that I've ever seen, and I was wondering if anyone has any insight. The concern is that the brace being connected to the face of the beam puts the beam in torsion. In this case, they are showing a double-angle bolted shear connection at the end of the beam, but they are still relying on the web to transfer the torsion into this connection.
The constraint is that the brace and column cannot lie in the same plane as the beam due to the layout of the interior space.
The loads are on the light end, and this is in a low-seismic region (SDC B or less).
What's your opinion on the feasibility for this connection to meet AISC provisions? If the beam had a torsion-resisting connection at the end would it work?

If the lateral load is small, maybe you can justify it. Still, it looks awfully messy.

If I had to do this, I'd likely take the brace to the side of the column instead of the side of the beam so I could eliminate the annoying flange plate. Plus it's HSS so it would easily carry the torsion and resolve it into the beams up top.

1) Torsion in the beam.
2) Flexure in the brace.
It may well be that the brace is stiff enough to compete.
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.
