An exterior 24 X 18 in. column with D = 170 kips, L = 130 kips, and an interior 24 X 24 in. column with D = 250 kips, L = 200 kips are to be supported on a combined rectangular footing whose outer end cannot protrude beyond the outer face of the exterior column center to center of columns is 18 ft 0 in., and the allowable bearing pressure of the soil is 6000 psf. The bottom of the footing is 6 ft below grade, and a surcharge of 100 psf is specified on the surface. Design the footing for f. The distance = 3000 psi and f, = 60,000 psi.

24 X 18 in. column with D = 170 kips, L = 130 kips, and an interior 24 X 24 in. column with
D = 250 kips, L = 200 kips are to be supported on a combined rectangular footing whose outer
end cannot protrude beyond the outer face of the exterior column
center to center of columns is 18 ft 0 in., and the allowable bearing pressure of the soil is 6000 psf.
The bottom of the footing is 6 ft below grade, and a surcharge of 100 psf is specified on the
surface. Design the footing for f.
The distance
= 3000 psi and f,
= 60,000 psi.
