CMU Gable Wall Diaphragm Shear Connection

[DCBII]

I need ideas for a detail to transfer diaphragm shear from a steel roof deck into a gable end CMU wall. The deck will sit on open web steel joists running parallel to the gable end wall, so it will be 4 to 8 inches higher than the top of the wall.

I was thinking of something like this sketch (attached), but it seems like the sloped anchors would be hard keep in place unless they were fastened to the plate, but then how do they place the grout with the plate in the way. Also, the sloped anchors would tend to get in the way of the CMU webs from time to time. I suppose they can just knock those out.

Is there an easier way to do this?

What if you have the masons cut the courses BELOW your top of wall bond beam. Then have a top of wall bond beam that is 8" deep poured solid. Then use 3/8"x8"x8" embed plates (with headed studs) at say 48" o/c (or thicker if you want) and weld a continuous c4 channel to it (or 4x4 tube). Then weld the deck to that. Force the issue with the joist seats to match your wall working points. Or force the mason to align.

Can you bear the deck right on the CMU? I might embed a 4" wide continuous plate (with headed studs) in the sloping bond beam and weld the deck to the plate. That way your first joist doesn't need to be up against the wall and you don't need to wonder how it all acts when the joist deflects and the wall doesn't. It saves fussing with the big bearing plate, the bent plate, and those cast-in anchors.

The overhang presents a problem, but you can probably come up with a detail where the plate is stiffened and projects out.
