Thickened and Turned down slab thickness and width
Thickened and Turned down slab thickness and width
(OP)
I am looking for a good reference or a few good tips regarding thickend or turned down slabs at interior bearing walls.
I am working on a load bearing metal stud wall building with wood trusses for the roof. I have an interior load bearing wall and was planning on thickening the slab at this location.
My only reference is a TM-809 which dictates thickening my 4" to an 8" for a width of 5 feet. I think this width is a little excessive. Any ideas or thoughts or suggestions?
My wall loads are 945 lb/ft. This building is located on shale mostly - engineered fill partly, mountain top location.
Thanks!
Jody

With a thickened slab, any downward movement will be usually reflected in cracks at the slab-thickened edge interface. So using a bit more conservatism in your "footing" design (per UcfSE above) would be a good consideration to minimize or avoid these cracks.
