A floor system with columns on a $24$ ft grid is shown.

Beams in the north$-$south direction spaced at $8$ ft on

centers are used to create one$-$way slab action. The floor

is subjected, in addition to its own weight, to dead and

live loads of $20lb\frac{f}{f}{t}^2$ and $50lb\frac{f}{f}{t}^2,$ respectively.

$f_c^{\text{'}}=3000lb\frac{f}{i}{n}^2,$ and $f_y=60,000lb\frac{f}{i}{n}^2.$ No$.4$ bars

are used for flexural reinforcement, and no$.3$ bars are to

be used for temperature steel. Select the thickness of the

slab and design the flexural reinforcement.
