$17\mathrm{.}1$ A continuous footing is shown in Figure $17\mathrm{.}22.$ Using

Terzagh's bearing capacity factors, determine the gross

allowable load per unit area $(q_{Ul})$ that the footing can carry.

Assume general shear failure. Given: $=115l\frac{b}{f}{t}^3,$

$c^{\text{'}}=600l\frac{b}{f}{t}^2,{}^{\text{'}}=25,D_f=3\mathrm{.}5ft,B=4ft,$ and factor

$17\mathrm{.}4$ Repeat Problem $17\mathrm{.}1$ using Eq$.(17\mathrm{.}31),$ Table $17\mathrm{.}2,$ and Eqs. $(17\mathrm{.}35)$ through $(17\mathrm{.}37)$
