Chapter 16, Problem 16.14P

Redo Problem 16.13 with the following data: gross allowable load = 184,000 lb, γ = 121 lb/ft3, c′ = 0, ϕ = 26 ° , Df = 6.5 ft., and required factor of safety = 2.5.

16.13 A square footing (B × B) must carry a gross allowable load of 1160 kN. The base of the footing is to be located at a depth of 2 m below the ground surface. If the required factor of safety is 4.5, determine the size of the footing. Use Terzaghi’s bearing capacity factors and assume general shear failure of soil. Given: γ = 17 kN/m3, c′ = 48 kN/m2, ϕ = 31 ° .
