Light gauge roof joist to wall stud connection

[BSPE90]

I am currently developing a framing section and have a question on a light gauge steel connection. What would the best way to support the end of the low roof joist shown below? Right now I'm showing a skewed track connected to the outside face of the stud wall to receive the sloped roof joists. Is this an okay approach? Or would it be better if the the joists match the stud spacing (they are both spaced at 16" o.c.), extend the roof joists and screw the webs of the stud and joists together. One concern is that at the other end, it is bearing over a stud wall where the studs have to also align with the joist locations. So everything will have to kind of line up correctly.

Something like the attached... I've seen screed strips similar to the attached, too.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Agreed with dik. Main reason for me is that screws/welds are directly attached to the stud for better load transfer. Otherwise, you rely on the bending capacity of rim track flanges.

thanks... just the way I've seen it done...

dik's option is a good one and I've used it before. Another way, if changing the spacing is too costly or incompatible with some other element of the structure, is to put blocking between the studs and use clip connectors for each joist. Then at the continuous joist over the wall, there are connectors that create the slope similar to the way a beveled plate provides bearing for a joist in wood construction.

If you go with dik's version above, pay attention to your detailing over the wall. I treat that situation similar to a slip track - make sure you have punchouts within a foot of the top of wall and run an extra line of bridging there since you won't have a track to stabilize the studs in the plane of the wall. Of course, blocking between the joists can help there, too.
