A 4-foot square footing has its bottom 2.03 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 114 lb/ft3, Saturated unit weight is 122 lb/ft3, cohesion = 97 lb/ft2. Use angle of internal friction = 30° (Nc = 35.4, Nq = 29.1,  = 19.7). Compute the allowable load (in lb) that the footing could carry. Use FS = 2.9. Round off to the nearest whole number.

A 2.0 m 2.0 m square pad footing will be placed in a normally consolidated clay soil to carry a column load Q. The depth of the footing is 1.0 m. The soil parameters are: c = 0, = 26, = 19 kN/m3, and cu = 60 kN/m2. Determine the maximum possible value for Q, considering short-term and long-term stability of the footing.

Refer to the rectangular combined footing in Figure 10.1, with Q1 = 100 kip and Q2 = 150 kip. The distance between the two column loads L3 = 13.5 ft. The proximity of the property line at the left edge requires that L2 = 3.0 ft. The net allowable soil pressure is 2500 lb/ft2. Determine the breadth and length of a rectangular combined footing.
