Design a single-column footing (including dowels) to support an 11 in. square column reinforced with eight No. 9 (No. 29) bars centered 2.5 in. from the column faces (equal number of bars on each face). The unfactored axial dead load = 135 kips, and the unfactored axial live load = 125 kips. For the column, = 4000 psi and f, grade. The allowable soil bearing pressure is 3000 lb/ft?. Material strengths for the footing are f. = 60,000 psi. The base of the footing will be 3 ft below = 3000 psi and f, = 60,000 psi.
