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.

An isolated footing having dimensions of 1.5m x 2.2m is provided at a depth of 1.2m in a stratum of cohesionless soil having a relative density of 71%. Determine the bearing capacity factors Nc, Nq and Nγ as per IS code.
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:
Calculate the ultimate bearing capacity considering the following: A strip footing, 2 meters wide A square footing 3m by 3m A circular footing 3m in diameter. All footings are located at the ground surface and groundwater level is at the ground surface. The soil is coarse grained with saturated unit weight of 19.8 kn/m3 and angle of internal friction of 25 degrees.
A building will have a factored column load of 300 kN. The column is to be supported on a square spread footing underlain by a soil with the follow properties: c' = 5 kPa, o' 35°, y = 18.5 kN/m³. The groundwater table is at a depth of 15 m and the footing will be located 0.5 m below the ground surface. Determine the required footing size if Þ = 0.5. Use Terzaghi's bearing capacity equation for a square footing. Solve for 'B', making sure to use the reduction factor Þ; trial and error is the easiest way to solve for 'B'. Recommend a "reasonable" dimension for construction/design purposes.
