Slab on Grade Point Load
Slab on Grade Point Load
(OP)
I have an 'infinite' slab on grade with a point load applied in the middle having an area of A in2. It is supported on a uniformly compacted granular base.
Does anyone have a formula for the maximum -ve moment at the top of the slab, and a maximum +ve moment at the bottom of the slab?
Thanks, Dik

It isn't giving you max. moments (you could back figure them if you need them) or both the + & - moments......but for a slab loaded far from edges.....stress in the bottom of the slab should be all you need.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

You can do a manual calculation as outlined in Yoder and Witczak, Principles of Pavement Design
