2. Change the footing dimension in the question below to a strip footing with width of 6 ft. and find the settlement using Schmertmann's modified method to calculate the required settlement. Example 8-2: A 6 ft x 24 ft footing is founded at a depth of 3 ft below ground elevation with the soil profile and average N160 values shown. Determine the settlement in inches (a) at the end of construction and (b) 1 year after construction. There is no groundwater. The footing is subjected to an applied stress of 2,000 psf. Ground Surface Clayey Silt 3 ft Y = 115 pcf; N160= 8 Sandy Silt B = 6 ft 3 ft Y = 125 pcf; N160= 25 Coarse Sand 5 ft Yt = 120 pcf; N160= 30 Sandy Gravel 25 ft Yt = 128 pcf; N160= 68

subject
A footing is carrying a design column load of 22 k and a moment of 5 k-ft in one direction.The footing will be founded on sand at a depth of 2 ft. The water table is 3 ft below the groundsurface. Design the footing width for a square footing that will carry the design loads and meetthe presumptive allowable bearing pressure per the International Building Code.
A proposed office building will include an 8 ft 6 in square, 3 ft deep spread footing that will sup-port a vertical downward service load of 160 k. The soil below this footing is an overconsolidated clay with the following engineering properties: Cc /(1 + e0) = 0.10, Cr/(1 + e0) = 0.022,sm′ = 4,500 lb/ft2and g = 113 lb/ft3 . This soil strata extends to a great depth and the ground-water table is at a depth of 50 ft below the ground surface. Determine the total settlement of this footing.
