Question

The allowable bearing pressure on a 100-ft thick (below the base of footing Es = 55 MPa) medium dense sand (take phi = 36°, y = 112 pcf) is 3 ksf. Column A has a design load of 430 kips and Column B has 190 kips. What size footings would you use and what might one expect for differential settlement? By using Table 5-7, is this differential settlement satisfactory?
