W1, W2 and X are given at the bottom.

Design a square column footing for a 18-in. square tied interior column that supports loads of DL (W1) k and Live load LL (W2) 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 w ksf.

The concrete strength is 4,000 psi and the steel is Grade 60.

W1 = 220 k

W2 = 165 k

X = 4.5%
