A 2-foot square footing has its bottom 2.12 ft. below the ground surface. The ground water table is located at a depth of 4 ft. below the ground surface. Unit weight of soil is 118 lb/ft3, Saturated unit weight is 123 lb/ft3, cohesion = 98 lb/ft2. Use angle of internal friction = 30° (Nc = 35.3, Nq = 29.1, begin mathsize 12px style text N end text subscript straight gamma end style = 19.1). Compute the allowable load (in lb) that the footing could carry. Use FS = 2.7. Round off to the nearest whole number.

A 2-foot square footing has its bottom 2.12 ft. below the ground surface. The ground water table is located at a depth of 4 ft. below the ground surface. Unit weight of soil is 118 lb/ft3, Saturated unit weight is 123 lb/ft3, cohesion = 98 lb/ft2. Use angle of internal friction = 30° (Nc = 35.3, Nq = 29.1, begin mathsize 12px style text N end text subscript straight gamma end style = 19.1).
Compute the allowable load (in lb) that the footing could carry. Use FS = 2.7.
