$13\mathrm{.}2$ The $5-$in thick simply supported rectangular slab shown

in Fig. P$13\mathrm{.}2$ is reinforced with no$.3$ bars at ${10}^{\text{'}\text{'}}$ in the

$y-y$ direction and no$.3$ bars at ${15}^{\text{'}\text{'}}$ in the $x-x$ direction.

$($a$)$ Calculate the ultimate capacity for uniform load.

$($b$)$ Compute the ultimate uniform load assuming the

slab behaves as a one$-$way system $($Hint: Consider

a $1-$ft strip and treat it as a simple beam$).$ How does

this value compare to that computed in $(a)?$
