Sawcuts in Stiffened RC slabs
Sawcuts in Stiffened RC slabs
(OP)
I wonder if sawcuts are used or permitted in reinforced concrete slabs with stiffening beams.
Reason Im asking is that part of my slab on ground is floating slab i.e. no stiffening beams so sawcuts are to be used and a part is stiffened to allow for extra load, but then can I space the sawcuts evenly so that it also covers the stiffened slab ?

RE: Sawcuts in Stiffened RC slabs
1) the saw cuts reduce your effective flexural depth a bit.
2) saw cuts will be much less effective with continuous stiffening ribs thrown into the mix.
3) not having saw cuts saves money.

The problem is we want to pour the stiffened slab together with the floating slab (without beams) all together.
Then we have to sawcut the floating slab but to get regular sawcuts it would also continue on to the stiffened slab.
If it didn't sawcut would finish abruptly and that would look weird.

I've never sawcut a stiffened slab before as it is not necessary.
