A 5-ft wide, 8-ft long, 3-ft deep footing supports a downward load of 200k and a horizontal shear load of 25k. The shear load acts parallel to the 8-ft dimension. The underlying soils have cr=500 lb/ft2, Φr=28o, γ =123 lb/ft3. Using a total stress analysis, compute the factor of safety against a bearing capacity failure.4.

A square footing of 2 m sides rests on the surface of a homogeneous soil bed having the properties :
Cohesion c = 24 kPa, angle of internal
friction is 25°, and unit weight is 18 kN/m^3. Terzaghi's bearing capacity factors for internal angle of friction 25° are :
Nc= 25.1, No= 12.7, Ny= 9.7,
Nc’ =14.8, Nq'= 5.6 and Ny’= 3.2.
Determine The ultimate bearing capacity of the foundation
Q.3. Three parallel strip footings 3 m wide each and 5 m apart center to center transmit
contact pressures of 300, 450 and 150 kN/m2 respectively. Calculate the vertical stress
due to the combined loads beneath the centers of each footing at a depth of 4 m below
the base. Assume the footings are placed at a depth of 2 m below the ground surface.
