2. A strip footing will be used to support a load-bearing wall with a load (P/b) of 3500 lbs/ft. The footing is 1.5 ft thick (T), and the unit weight of the soil is 120 pcf. Use 145 pcf for concrete. The frost depth (D) is 2.5 ft. Groundwater is located 3 ft below the base of the footing. Find the smallest footing size (B) such that the gross bearing pressure does not exceed 2000 psf. Give your answer to the nearest 1/4 foot. T P/b B D
