A square footing is shown in Figure 16.20. The footing is subjected to an eccentric load. For the following cases, determine the gross allowable load that the footing could carry with Fs = 5. Use shape factors by De Beer (1970), depth factors by Hansen (1970), and inclination factors by Meyerhof (1963).
a. ( = 19 kN/m3, c' = 0, (' = 31°, Df = 1 m, B = 2.5 m, x = 0.2 m, y = 0
b. ( = 18 kN/m3, c' = 43.1 kN/m3, (' = 26°, Df = 1.22 m, B = 1.83 m,
x = 0.27 m, y = 0
c. ( = 1800 kg/m3, c' = 0, ( = 38°, Df = 1.5 m, B = 1.5 m, x = 0,
y = 0.1 m
