Problem $4$: Given a concrete floor system of $3^{\text{'}\text{'}}$ slab, clear span $l_n=24ft$ and transverse

web spacing $s_w=47in,$ and beam width $b_w=11in,$ effective depth of $d=20in,$ made

with concrete with $f_c^{\text{'}}=3$ksi, and grade $60$ steel, design the floor beams, design the

reinforcement if total deadload $($including self weight$)$ was $500$ psf and total live load was

$765$ psf on slab.
