Turndown Slab design
Turndown Slab design
(OP)
We often use turndown slab, AKA thickened slab footing, for light frame structure with no frost depth requirements.
The slab on grade which pout monolithic with the turndown slab will ended up carrying additional moment resulted from the eccentricity, and I have been using finite element program, like ADAPT to design the footing and slab on grade. This is time consuming.
Therefore, I was wondering if there is any publications that show simplifed version.
Could you please kindly let me know where could i find something about this? I would appreciate it.

RE: Turndown Slab design
I kind of confused about your post, if i understand correctly you have a small building, one storey, with light framing?
I would assume this would be designed like a residential building, taking into account the movement of the soil due to moisture effects?
If this is the type of building and the situation we are looking at then I wouldn't know of the correct reference for the USA, however I know the U.S. Army Corps of Engineers have bit of information on foundation on expansive soils, but I would think there is a national code for this. In Australia there is.
When in doubt, just take the next small step.

For higher loads you may want to consider cross beams.
