2. A square foundation of width 6 feet applies a uniform pressure of 500 psf to the underlying ground. Determine the vertical stress increase at a depth of B/2 below the center using. The three methods below a. Ao (Hint: Solving for m and n and obtaining influence factor from Table 8.5 in book) b. 2:1 Method c. Stress Isobars
EXAMPLE 8.5 Solve Example 8.4 using Eqs. (8.10) and (8.26) and Table 8.5. SOLUTION Consider a quarter of the square and multiply by four for the I-value for the center 9. 100 kN/m² B' = B/2 (m) L' = L/2 (m) Ao = 49.1 (kN/m²) z(m) m n 1 (Table 8.5) 3.0 1.5 0.08403 33.6 1.5 0.5 0.5 1.5 0.375 0.375 4.0 1.5 0.0540 21.6 5.0 1.5 1.5 0.3 0.3 0.03735 14.9
