A floor system is designed with T$-$beams with the cross section shown. Slab reinforcing and

compression reinforcing are not shown for clarity. Ignore the impact of the reinforcing steel other

than the tension steel shown for the following calculations. The beam's clear span $($into the page$)$ is

$13$ ft $.$ The concrete has f$^(\text{'})$c$=4,000\backslash$psi and fy$=60,000\backslash$psi $.$

ror the deam on column $$ne A :

$($a$)$ Determine the effective flange width per ACl Code

For the beam on column line B:

$($b$)$ Determine the effective flange width per ACl Code

$($c$)$ Calculate the structural depth, d to the center of the reinforcing

$($d$)$ Calculate the nominal moment capacity Mn

$($e$)$ Find the depth to the neutral axis and check if the steel has yielded when the concrete reaches a

maximum strain of $0\mathrm{.}003$

$($f$)$ Calculate the practical moment strength $\backslash$Phi Mn
