The engineered joist is connected via hanger to the truss. The other side of it is over a steel beam. I don't remember if it ends there or not.What you have is an engineered joists and not a beam. A joist is not load carrying as we talk about, so I would guess that short wall carries a load.
The engineered joist isn't connected to the wall below, but to the truss.
Has anybody come across this sort of setup?
