Water uplift pressure where single footing system is adopted

Water uplift pressure where single footing system is adopted

(OP)
Hi guys,
When designing a single footing shall I consider water uplift pressure ?
What I have in my mind is that if the water table level have increased, the water is allowed to move up from the sides of the isolated footings, hence no pressure is applied to the footing .. however this pressure could be applied to the slab on grade (if this water could reach the slab on grade).
Am I right ? Is there any close in the code that explain this situation ?
Thanks ..

RE: Water uplift pressure where single footing system is adopted

If the water is higher than that underside of the footing, it will exert buoyant pressure on that footing.

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.

RE: Water uplift pressure where single footing system is adopted

your footing will get lighter to resist any overturning or sliding effects.
