A 60 kip column is supported on a square footing with a length and base of 4 ft. Using the 2:1 Method, what is the increase in vertical stress (Ao₂) at a depth of 5 ft below the footing? O 3750 psf O 740 psf 625 psf O 400 psf
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.
