A (9’x9’x32”) square footing is supporting 230 kips dead load
and 130 kips live load from 18-in square column. The allowable
bearing soil pressure is 5000 psf. There is no over-burden soil
weight. Check if the footing area satisfies the soil bearing
pressure requirements. Also, check if the thickness satisfies the
shear ( two and one way) requirements. Finally, design the flexural
steels each direction.
