Calculate vertical stresses at depths of 3, 6, and 12 ft under the center of The footing?

A 1.5-m diameter circular footing has its base buried at a depth of 2.5 m from the natural grade line while the water table is located a depth of 1.2 m below the natural grade line. The soil above the water table is 21.437 kNm3 while the saturated unit weight is 23.309 kNm3. The soil has a cohesion of 25 m3 kPa. Assuming local shear failure, a factor of safety of 3.2, and bearing capacity factors Nc'= 11.85, Nq'= 3.88 and Ny'= 1.12 a. Compute the ultimate bearing capacity of the soil. b. Compute the allowable bearing capacity of the soil. c. Compute the allowable load on the footing.

A rectangular footing has a footprint of 16ft x 20 ft. If the footing carries a load of 160 tons at the base, what is the stress in psf 10 feet below the center of the footing? Round your answer to the ones place (answer is set to exact). I also recommend using the table instead of the graph. Type your answer...

A proposed office building will include a 10 ft x10 ft square, 3 ft deep (the footing height is also 3 feet) spread footing. The normally consolidated clay has the following engineering properties: Ydry = 115.0 pcf $'=24° c'=90.0 psf Cc/(1+eo) = 0.15 The soil stratum extends to a great depth, and the ground water table is 50 ft below the ground surface. Using the classical piece-wise log-linear method, estimate the total settlement of this footing considering only the allowable bearing pressures using ASD approach. The unit weight of concrete is 150 pcf. State any assumptions made.
