Question

A 5 ft wide, 8 ft long, 3 ft deep footing supports a downward load of 200 k and a horizontal
shear load of 25 k. The shear load acts parallel to the 8 ft dimension. The underlying soils have
c′ = 220 lb/ft2

, f′ = 28°, and g = 123 lb/ft3

. Using an effective stress analysis, compute the

factor of safety against a bearing capacity failure.
