Q$4.$

A continuous foundation is shown in Figure $6\mathrm{.}24.$ If the load eccentricity is $0\mathrm{.}2m,$ determine the ultimate load, $Q_w,$ per unit length of the foundation. Use Meyerhof's effective area method.

SOLUTION

For $c^{\text{'}}=0,$ Eq$.(6\mathrm{.}55)$ gives

$q_u^{\text{'}}=q{N}_q{F}_q{F}_{qd}{F}_{qi}+\frac{1}{2}{}^{\text{'}}{B}^{\text{'}}{N}_{}{F}_{}{F}_d{F}_i$

where $q=(16\mathrm{.}5)(1\mathrm{.}5)=24\mathrm{.}75k\frac{N}{m^2}.$
