Slab on grade with linear loading
Slab on grade with linear loading
(OP)
Hi,
I have an existing 6 inch slab on grade. I want to know if it can support a linear loading. The equipment that I have to support sit on a steel "W" beam width of 5 inch. The load carried to the slab is 25 kip /ft.
How do you evaluate if the slab can carry such load ?
Thank you for helping

Factored shear resistance will be in the range of 50 to 70 psi, for a typical 3000 to 4000 psi in-place strength of concrete. Considering two shear planes of 144 square inches total, you might get as much as 10k/ft...but don't count on it....the thickness varies as does the strength.

That's neglecting bending in the perpendicular direction, which will likely yield even less resistance.
As TJ noted...put a foundation under it.
