1. A square column foundation has to carry a gross allowable load of 1805 kN sFS 5 3d. Given: Df 5 1.5 m, g 5 15.9 kN/m3, f9 5 348, and c9 5 0. Use Terzaghi's equation to determine the size of the foundation (B). Assume general shear failure.
2. Use the general bearing capacity equation [Eq. (4.26)] to solve the following:
a. Problem 4.1a
b. Problem 4.1b
c. Problem 4.1c
3. The applied load on a shallow square foundation makes an angle of 208 with the vertical. Given: B 55 ft, Df 5 3 ft, g 5 115 lb/ft3, f9 5 258, and c9 5 600 lb/ft2. Use FS 5 3 and determine the gross inclined allowable load. Use Eq. (4.26).
