Problem # 3 A combined footing supports an exterior column 16 in x 16 in carrying a service dead load of 155 kips and a service live load of 165 kips, plus a 22-in.-square interior column carrying service loads of 205 kips dead load and 230 kips live load. The distance between the columns is 18 ft, center to center. For shallow foundations, the allowable soil bearing pressure is 4 ksf and the bottom of the footing is 4 ft below final grade. Design the steel in long direction using fc' = 3 ksi, fy 60 ksi.
