A plate$-$load test was conducted in a sandy soil in which the size of the

bearing plate was $0\mathrm{.}3m0\mathrm{.}3m.$ The ultimate bearing stress for the test was

found to be $184\mathrm{.}5$kPa. Estimate the total allowable load $($Qall$)$ for a footing

of size $1\mathrm{.}8m1\mathrm{.}8m.$ Use a factor of safety of $4.$

For clayey soil: $,q_{u(F)}=q_{u(P)}$

For sandy soils: $,q_{u(F)}=q_{u(P)}\frac{B_F}{B_P}$

$B_{\frac{?}{\text{b}\text{a}\text{r}}(F)}=$ width of the foundation

$B_p=$ width of the test plate
