3. The bearing capacity of shallow foundations (i.e. footings) depends on the soil shear strength (ie. ф and c). The ultimate bearing capacity (qultnei) of the soil is calculated using the following equation: Dr qult.net bearing capacity failure surface i. Frictional resistance along failure surface due to self-weight of soil below footing level footing level. Ny. No, and Ng are dimensionless bearing capacity factors that depend on the ii. Cohesive resistance along failure surface below footing level. iii. Frictional resistance...
Part-I: OPEN BOOK Problem 1 (30 points). For the isolated square footing shown below, assume that the combined weight of soil and concrete above the base of the footing is equal to 120 pcf. Assume fc-3000 psf and column size of 18in. x 18 in. Determine the followings: a) If the footing size of 10ft. x10ftx 2ft. is adequate based on allowable soil-bearing capacity qa 6,000 psf b) If the footing 10ft. x10ft.x 2ft. is adequate for shear e) Calculate...
A square footing with a width of 4 ft is subjected to a concentric load of 200 kips. The bottom of the footing is located 6 ft below the ground surface. The ground water table is located at a depth of 8 ft below the ground surface. The given soil properties are γt of 115 pcf, γsat of 122 pcf, ϕ' of 25°, c' of 800 psf, Gs of 2.68 and wn of 15%. Determine the allowable bearing capacity using...
