Dividing wall

Dividing wall

Dividing wall

(OP)
I am designing a short wall (approx. 4.5 ft to 5' tall) that will wrap around an audio/visual area. The area will be about 8'x10' or so. What is the best way to anchor the wall studs to the existing concrete floor so as to make it stable. I know I have the corners to help, but one wall will have a half door which will interrupt the top plates. My thought was Tapcon anchors in the PT sill plate and Simpson SPH4R at each vertical stud. Outside face of wall will be sheathed with 1/2" plywood. Suggestions would be appreciated. Thanks and have a great day.

RE: Dividing wall

You shouldn't keep a continuous bottom plate without good reason... It is a tripping hazard.

This is a pretty straight-forward design. Use an appropriate post-fixed anchor for the thickness and age of slab, and solve this as a cantilever with whatever latteral load your code requires for walls (placed at the top, as this is a part wall).

Will you have glazing above?

RE: Dividing wall

I like the Tapcons but since you have ply on one side I think the SPHR4 is overkill. What about SP1 at each stud, only on the unsheathed side?

No glazing above, it will all be open.

RE: Dividing wall

2x6 instead of 2x4 will improve the moment arm immensely.

RE: Dividing wall

Braves25:
Why not ½" sheathing on both sides, that really stiffens (and ties together) the wall diaphragm from both directions (and both sides) when properly nailed at the top and bottom pls. This becomes a stressed skin box beam, a torsion box, and can be loaded from either direction. Use a 2x6 wall because it widens the base pl. from the canti. standpoint. Use conservative (more than code) lateral loading, you know that door jamb is going to be a leaning post, and people will grab it when turning the corner. As needed, maybe mid point of each wall and at each door jamb, provide a rod with threaded ends, full height and tightenable at the top pl. with large pl. washers, in affect prestressing the wall down to the fl. An anchor in the fl., with short threaded rod and a coupling nut on top to receive the full length rod.

RE: Dividing wall

I would put a 1/2" dia Titen with a rectangular washer plate adjacent to the door jambs.

RE: Dividing wall

If you want to go robust add some hold downs at the opening, and around the rest design the top plate as a girt/sideways beam. I would recommend some sort of/clip or angle connecting the sill-plate anchor to the stud directly so you are relaying on some toe nails. but these are all just opinions.

RE: Dividing wall

Does the top have to be completely open? You could add bracing at the top of the wall at the corners.
