1. A square foundation is shown in Figure P4.12. Use FS 5 6, and determine the size of the foundation. Use Prakash and Saran theory [Eq. (4.55)].
2. The shallow foundation shown in Figure 4.24 measures 1.5 m 3 2.25 m and is sub- jected to a centric load and a moment. If eB 5 0.12 m, eL 5 0.36 m, and the depth of the foundation is 0.8 m, determine the allowable load the foundation can carry. Use a factor of safety of 4. For the soil, we are told that unit weightg 5 17 kN/m3, friction angle f9 5 358, and cohesion c9 5 0.
