A strip footing is founded on sand having strength parameters (0 =44 and c = 0 kPa). Dry and saturated unit weights of the soil are 18 and 20.1 kN/m respectively. The foundation is designed to to carry a load of 6.5MN/m at a Factor of safety against general shear failure of 3. The footing depth is 1.5 m and the water table is 2.5 m from the surface. Determine the minimum footing width (m) to satisfy the design requirements (2 d.p). Use unit weight of water of 9.8 kN/m. Silent question: Is water table affecting foundation support? Verify your assumption.
