Hawkz,
Good point. The other end is a connection into a HSS column @ one location and web of a W8 at another location. I haven't detailed those yet and may be I'll leave those for the steel contr to deal with.
For this connection though, I am wondering if instead of the weld I could specify thru bolts.

You could just use a standard seated connection with the top angle in place. If you leave both angles unstiffened. Use side turned down welds one on each side to weld the tube to the bottom angle. The top whether continous or not simply welds on the outside tip of the leg. This is considered to be a flexible simple connection since it is assumed that the angles will allow the beam to still rotate at its ends. With the high and low angle you'll be able to handle the vertical and horizontal reactions and any torque in the beam. A larger embed will allow the studs to gain maximum strength and also give you some more play in the field when fitting up.
Now if we stick with your concept which is something I had never considered, you could replace the U-shaped plate with two seperate angles. Just like a W-shape beam with a double angled connection. That would allow for easier fit up. In fact the with the seat angle the entire connection could be field welded if you don't have enough slip on the other connection. Because this entire side will be welded I prefer the seated connection since it allows for more field play.
