Slab on grade design
Slab on grade design
(OP)
Sorry, I just posted this on the wrong forum.
When I worked for an oil company, I saw big water tanks that accompany rigs put right on the grade. Now when designing a slab on grade for a warehouse, My boss asks for 8 inches thickness and two layers of reinforcement.
How do you design slab on grades?
Thanks

RE: Slab on grade design
The slab is assumed to be supported by a series of springs (that have no ability to accept tension, only compression). You, therefore, need to assume a spring constant for the soil, although this won't have too much affect on the slab thickness.
I would suggest a book titled "Designing Floor Slabs On Grade" by Boyd Ringo and Robert Anderson. There are many methods, charts and tables that address these issues.
Best of Luck!

ACI 360 is design of slabs on grade. It deals more with subgrade questions, etc.

PCA also publishes excellent guides as well.
