load LL (210) k. The column is reinforced with eight No 8 bars, the
bottom of the footing is 5 foot below final grade, and the soil
weighs 100 lb. /ft3 the allowable soil pressure is 4 w ksf. The
concrete strength is 4,000 psi and the steel is Grade
60.

. Design a square footing for a 16-in. square
interior column with an ultimate dead load = 300
(k) and an ultimate live load = 200
(k). Take fy=60,000 psi,
fc=4000 psi, normal weight, and
qa= 4500 psf. Assume the base of the
footing is 4 (ft.) below grade. Draw the
reinforcement detail also. Check for one way and two way shears
with the support of diagram. With ACI code
