Steel Bar Joist on Light Metal Framing

Steel Bar Joist on Light Metal Framing

Steel Bar Joist on Light Metal Framing

(OP)
Good Afternoon!
I have a project that requires steel bar joists supported off light gauge metal framing.  This is the first project I’ve done this one.  I’m expecting end uplift reactions of roughly 850 lbs.  Anyone have suggestions on how to make this transition down to the metal stud?

RE: Steel Bar Joist on Light Metal Framing

Put a steel tube or angle on top of the load bearing light gage top track and weld the bar joists to the structural steel.

Alternately use a heavy light gage top track or heavy light gage built up top section and weld the joists to that (use > 14 gage material).

RE: Steel Bar Joist on Light Metal Framing

I agree with ArneG--also weld the angle, tube or heavy track to the studs to take the uplift into the studs.

Also, consider placing a stud directly under each joist where possible.  This seems to be an over-simple comment, but may be an overlooked necessity depending on the application.

RE: Steel Bar Joist on Light Metal Framing

I agree with the previous comments.

Also, don't forget to tie those members together to act as the chord of the diaphragm.
