A square column foundation has to carry a gross allowable load of 1805 kN (FS = 3). Given: Df = 1.5 m, γ = 15.9 kN/m3 ϕ = 34 and c′ = 0. Use Terzaghi’s equation to determine the size of the foundation (B). The applied load on a shallow square foundation makes an angle of 15° with the vertical. Given: B = 1.83 m, Df = 0.91 m, γ = 18.08 kN/m3 ,ϕ=25° , and c′ = 23.96 kN/m2 . Use FS = 4 and determine the gross allowable (vertical component) load. Use Eq. (16.9).
