1. For a square foundation that is B 3 B in plan, Df 5 2 m; vertical gross allowable load, Qall 5 3330 kN, g 5 16.5 kN/m3; f9 5 308; c9 5 0; and FS 5 4. Determine the size of the foundation. Use Eq. (4.26).
2. For the design of a shallow foundation, given the following:
Soil: f9 5 208
c9 5 72 kN/m2
Unit weight, g 5 17 kN/m3
Modulus of elasticity, Es 5 1400 kN/m2 Poisson's ratio, ms 5 0.35
Foundation: L 5 2 m
B 5 1 m
Df 5 1 m
Calculate the ultimate bearing capacity. Use Eq. (4.38).
