A continuous foundation is required in a soil where c' = 10 kN/m 2 , ' = 26, and = 19.0 kN/m 3 .

A continuous foundation is required in a soil where c' = 10 kN/m², ϕ' = 26°, and γ = 19.0 kN/m³. The depth of the footing will be 1.0 m. The dead load and the live load are 600 kN/m and 400 kN/m, respectively. Determine the required width for the foundation based on allowable stress design with FS = 3, using Eq. (6.10) and Table 6.1.
