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.

A square footing, 1.7 m x 1.7 m, is to be founded at a depth of 1.4 m below the ground surface of a deep clayey sand stratum. The saturated unit weight of the soil is 17 kN/m3. Based on drain triaxial tests, the soil parameters are c' = 7 kPa and ø' = 25°. The ground water table was found at the surface level. The foundation is to carry a permanent load of 280 kN and a variable load of 210 kN.

The soil is coarse grained with saturated unit weight of 19.8 kn/m3 and angle of internal friction of 25 degrees.
Develop a spread sheet to compute allowable total vertical column loads using the ASD methodand factored ultimate vertical column loads using LRFD. The spreadsheet should consider onlyvertical loads on a square or continuous footing bearing on single uniform soil. It should allowthe input of footing width, depth, water table depth, soil strength parameters, a factor of safetyfor ASD, and a geotechnical resistance factor for LRFD. It should compute the bearing capacitybased on both Terzaghi’s and Vesic ́’s methods.
