Chapter 11, Problem 11.2P

Repeat Problem 11.1 based on limit state design, using the factors given in Table 11.4.

11.1 A continuous foundation is required in a soil where $c^{\prime }=10\text{kN}/{\text{m}}^{\text{2}}$, ${\varphi }^{\prime }=26°$, and $\gamma =19.0\text{kN}/{\text{m}}^{\text{3}}$. 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.
