Practice

A continuous (strip) footing of width $B=7\,\text{ft}$ is founded at depth $D_f=3\,\text{ft}$ in soil with cohesion $c=400\,\text{psf}$, friction angle $\phi=32^\circ$, and unit weight $\gamma=120\,\text{pcf}$. Assume the same soil above and below the base, no surface surcharge, and no groundwater within the zone of influence. Using the bearing capacity factors in the PE Civil Reference Handbook, the ultimate (gross) bearing capacity $q_{ult}$ is most nearly:
