Question

A column load of 72 kips is applied to the 6 ft by 8 ft rectangular concrete footing shown below.
The groundwater table is 2 ft deep. The soil profile and properties are shown below.

The required minimum factor of safety against bearing capacity failure is 2.5. Is the current
foundation design acceptable? Use Vesic’s bearing capacity formula

1a. Intermediate calculation: compute the ultimate bearing capacity, qult, in units of psf.
1b. Intermediate calculation: compute the applied bearing pressure, q, in units of psf.
1c. Final calculation: compute the factor of safety (FS) against bearing capacity failure.
