Monolithic Footings and Eccentricity
Monolithic Footings and Eccentricity
(OP)
When designing the foundation for a building (such as a PEMB) with monolithic slab & footings (thickened slab footings) do you and how do you consider the eccentricity of column axial load on exterior & exterior corner footings?
I know this is in the "grey area" between this forum and the Foundation Eng forum so just say so if I should post this there....

If you do it by hand, figure out how much thickened slab edge you need to resist the vertical load without overstressing the soil (assume a uniform soil pressure). The centroid of this uniform soil pressure will not line up with the imposed load above, thus causing a moment that must be resisted by the non-thickened slab. Again, the moment is critical where the slab reduces in thickness.
