Problem #2 Design a footing to support an 18 in. square column tied interior column reinforced with 8 #9 bars. The column carries an unfactored axial dead load of 245 kips and an axial live load of 200 kips. The base of the footing is 4 ft. below final grade and allowable soil pressure is 5 k/ft2 Use f' 3.0 ksi and fy 60.0 ksi. Limit one side of the footing to 8.5 ft.
