INDUCED STRESSA proposed 5 ft X 5 ft spread footing will support an office building. The column load plus the weight of the foundation will be 80 kips. The bottom of the foundation is 2 ft below the ground surface. The unit weight of the soil is 121 lb/ft3, v = 0.35 and K = 0.83 (you may not need this info). The water table is at a depth greater than 30 ft. Calculate and plot the induced vertical normal stress below the center of the footing. Plot induced stress at increments of 2 ft to a total depth of 16 ft below the bottom of the footing.
