Sheetrock Wall Bracing
Sheetrock Wall Bracing
(OP)
Has anyone ever specified sheetrock shearwalls? I'm curious about the connection to the bottom plate.
Around here, 8 ft. walls use 93" studs and three plates for a total of 97 1/2". Assuming they hang the ceiling first, that leaves 97" of wall for 96" of sheetrock - so only 1/2" of lap on the bottom plate. Assuming they locate the screws perfectly, it allows 1/4" of wood and gypsum edge distance for the screw. I noticed on my new house construction that they did not even bother fastening the sheetrock to the bottom plate - likely for this reason. Fortunately, I am not counting on the sheetrock for lateral.

They have to so it abuts the ceiling board.
Yes, but each sheet is 48" wide (or tall depending on how you look at it) so two 48" sheets will give you 96" which leaves 1" at the bottom. No way they are going to use a 54" sheet and cut it down to 49" to remove that space.

Looked at the procedure used for fixing Gyprock, like your sheetrock. They use offcuts to lift the sheets 10mm off the concrete floor. Still allows for screwing the bottom, and for fixing the baseboards.

Most houses around here do not use cornices
Yeahhhh, that's never going to happen

That said, I've worked with one contractor that did it right. They'd been burned on it on a small development, and figured out how to control their subs and work with the inspectors (or hire third parties for the shear walls) to get it done. They're the exception that proves the rule, though.

That is my experience

2) If one wanted to build these walls special, what would be the best way? One option below that will, of course, still ruffle feathers and raise eyebrows.

The trick, is getting them to screw the bottom of the sheets, because in my experience, last screw on the sheet is about 3" off the sheathing on the stud line.

For sure. Although my trim guy was happy about that as it makes it easy for him to find the studs for baseboard since the sheetrocker did not mud the bottom screws.
