Problem $4\mathrm{.}26$ Problem $4\mathrm{.}27$ Repeat Problem $4\mathrm{.}26$ using the ACI Code's

minimum thickness requirement for cases where deflections are

not computed $($Table $4\mathrm{.}1).$ Do not use the $$ given in Problem $4\mathrm{.}25.$

$($Ans$.14\mathrm{.}5-$in$.$ slab with #$6$ at $9$ in$.$ main reinf.$)$ For Problems $4\mathrm{.}25$ and $4\mathrm{.}26,$ design interior one$-$way slabs for

the situations shown. Concrete weight $=150l\frac{b}{f}{t}^3,f_y=60,000,$

and $f_c^{\text{'}}=4000.$ Do not use the ACI Code's minimum thickness

for deflections $($Table $4\mathrm{.}1).$ Reinforcement ratios are given in the

figures. The only dead load is the weight of the slab.
