A square footing is shown on the right. The footing is subjected to an eccentric load. For the following cases, determine the gross Qult Unit weight of soil = y (or density = f allowable load that the footing could carry. Use Meyerhof's procedure and Fs = 4. Given: y = 120 lb/ft3 ; c' = 400 lb/ft? $ = 25° %D %3D ; B = 6 ft %3D D, = 4.5 ft ; x = 0 В y = 0,5 ft

Q: A rigid shallow footing has the dimension of 1m x 1m, shown in the following figure. The depth of footing, mechanical properties of supporting soil and the load transmitted through the footing are shown in the figure. Determine shape factor (Is) and depth factor (I). 500 mm E,= 6500 kN/m² H₂=0.3 E, - 5000 kN/m² 1₂ = 0.3 E, 10000 kN/m = H₂ = 0.3 Ao = 200 kN/m² 0.0 m 3.0 m 5.0 m 8.0 m

11. Suppose the soil beneath the footing is now a sand with average SPT N60 of 28 (see below). Predict the footing settlement (in inches) using Meyerhof's formulas. 2 ft 18 ft 6 ft P = 72 kips Sand, y = 118 pcf Sand N60 = 28 Gravel
