Connecting a diagonal wood beam to a CFS Stud wall 2

[Revv]

Hey guys,

So I have a situation where I have a wood stair stringer connecting into a CFS Studd wall. I'm thinking of using a track spanned between 2 studs and bent diagonally to match the slope of the stringer with screws from underneath into the stringer to support. What do you guys think about this connection? Do you have any other ideas for a good connnection?

Thank you!

what about also screws sideways into studs located against the outer sides of the stringers?

You could connect it as SWComposites said, but then your stairs start taking lateral loads from the CFS stud wall. It becomes a minor axis bending moment in the stringer. I'd be wary of doing that if it's connected to an exterior wall. I generally span the strings vertically from the lower and upper floors rather than relying on bearing walls next to them.

I'm having trouble visualizing this. Is the top of the stringer not flush with the bottom of the CFS track? If not, why not? Seems like you'd be higher than the floor. If so, I'd just frame it how any porch is, with a wood joist underneath the CFS connected to the stringer with joist hangers.

I've not done this before but this is where my mind goes. Reasons I like it:

1) Conventional connection between wood stringer and wood ledger thing.

2) The stiffness of the wood ledger engages more of track flange in bending rather than just having a local force on the track flange. I see running the ledger thing the whole width of the stair.

3) Obviates the need to custom bend the CFM flange which, admittedly is not a big deal.

Okay, so I visualized that it would be connecting from the side on the minor axis. This is a situation where a sketch is worth a thousand words.

Agreed, definitely need a sketch here.

I would envision a standard wood frame hanger would suffice if you also placed a wood sleeper running along the top of the stud framed wall

spieng89's solution sounds pretty great to me. My option probably does not show the condition accurately given that the top of the stair is almost certainly a floor deck such that the top of wall elevation is lower than I show it. The stair probably hits a rim piece of some sort.
