Variant of the Formula for the Design Resistance of the Soil for Slab Foundations

The normative formula for calculating the design soil resistance for slab foundations linearly depends on the width of the foundation. With an increase in width, a moment may come when the design resistance exceeds the ultimate load on the base, which shows the incorrect application of the normative formula for slab foundations. In the new formula, the depth of the foundation is taken as the length characteristic. According to the research results, the new formula gives a more accurate value of the design resistance for a slab foundation, which does not exceed the ultimate pressure.
