HSS conn to precast
HSS conn to precast
(OP)
I wanted to get a second opinion on a detail that I am working on. It is a HSS beam connection to an embed plate within a precast wall panel. Please see the attached. The HSS has both vert and horz loads on it. Is this an economical and practical solution?

The 1.5" setback is for the welder.

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.

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.
