A discrete spread footing or a mat foundation can be modeled using this support specification, Foundation supports incorporate the Modulus of Subgrade Reaction (Ks), ‘a quantity that specifies the amount of force required to displace a unit area of soil by a unit distance. Below is a quick calculation of the value of Ks, Ks ks SBC SF 8 SBCxSF/5 subgrade modulus in kN/m2/m. = soil bearing capacity in kN/m2 = safety factor = 3 (See Foundation Analysis and Design by Joseph E. Bowles) = allowable settlement = 25mm (See Foundation Analysis and Design by Joseph E.
