C.F.S. Floor Framing Side-Lap Connection?

I have a situation where I'm using a cold formed steel flor framing (Specifically Marinoware JoistRite members) for a renovation of a run down brick building. One thing that I've been unable to find a solid detail/"how to" of, is a side lap connection of C.F.S. members to transfer diaphragm loads into the side walls. I know that for wood its common to provide blocking, and then at the last joist that's laid against the wall to use something equivilant of a clip angle with anchorage into the brick substrate & wood screws into the joist, and was originally going to just take that detail and adapt it to C.F.S.

Do the same general conditions/rules apply in this case with cold formed steel joists, but with obvioulsy replacing wood screws w/sheet metal screws? Or is this an instance where some other form of transfering of diaphragm shear is necessary? Any help/wisdom on this would be greatly appreciated.

As an EIT, I'm open to being wrong now if it means being right when it counts.

Can you secure a CFS 'nailer' to the wall like wood construction and attach the floor sheathing to it, like normal wood framed construction?

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

I was thinking a C section with the blocking fitting in between like the other blocking... The supported sheathing diaphragm is then in line with everything...

I would take a track (not a cee section) and fasten it to the brick as required. This track would replace the cee section immediately adjacent to the wall. The first joist 16" from the wall would be a cee section.

Yeah, Dave's suggestion sounds like the way to go.

Sounds good, thanks for the input Dave! And to Koot & dik for the follow ups, I appreciate the support.
