4. A single boring was taken at a site with the corrected N values shown below (table). Calculate the ultimate bearing capacity of the 10'x10' foundation at a depth of 4. The groundwater is 2 feet below grade. You may assume the average unit weight of the soil above the water table is 125pcf and the saturated unit weight is 134pcf.
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
Two footings, one circular and the other strip, are founded on the surface of a purely Cohesionless soil. Diameter of the circular footing and width of strip footing is same. Then, the ratio of ultimate bearing capacity of circular to strip footing is:

A structural engineer finished a design of a library. They determine that each column will carry 1000 lbs. the soil beneath the footing has the properties: gamma= 130 pcf, c= 75psf, phi= 40 degrees. The groundwater table is of great depth so it’s no concern. Sketch figures. What is the minimum size of the footing for a factor of safety of 3? Case 1: assume square footing Case 2: assume round footing
