Design a rectangular footing for an 18-in square interior column with a dead load of 210 k and a live load of 180 k. Make the length of the long side equal to twice the width of the short side, fy = 60,000 psi, fc' = 4000 psi, normal weight, and qallowable= 3650 psf. Assume the base of the footing is 5 ft 0 in below-grade , γ concrete = 150 pcf and γ soil = 100 pcf. Also, assume h=24 in and cover = 4.5 in .

Answer the following questions :

a- Find the required area then the dimensions of the footing .

b- Check one way shear.

c- Check the punching shear.

d- Design the reinforcement in both directions .
