A long strip footing foundation will be used to support a concrete masonry- bearing wall for a business building. The footing will be 2m wide and 45 m long. The wall loading imposed onto the foundation will be 200 kN per meter of wall length. i) Using both the 2:1 approximate and Boussinesq methods, determine the vertical stress increase (∆σ) at 3m below the footing center. ii) Compare and discuss the ∆σ values calculated from the two methods.

7. Pile cap foundation design A pile cap foundation systems is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a stable foundation for bridge piers as shown in the figure below In this example, each bridge pier is built on piles with length of 15 m and diameter of 0.5 m. The modulus of elasticity of the pile is 6890 MPa. The soil provides a frictional...
