At the basement of a building I am designing, we have a concrete slab on grade which does not have slab under drains. The bottom of this slab is below the water table, therefore it must be designed to resist the buoyancy force due to the ground water. To do this, I am going to provide a thick enough slab so that it's self-weight is adequate to cancel out the buoyancy.
My question is, under ASCE-7, does a buoyancy force like this fall under an "H" load, or an "F" load. The biggest issue being that H needs to be combined with 0.6*Dead Load, while F only needs to be combined with 1.0*Dead Load. This makes a big difference in the thickness of the slab that is required.
Any input would be greatly appreciated!
Thanks.
