: A simply supported $22$ ft long concrete beam with the section given below is subjected to

the following loads:

Distributed Dead Load $($NOT including self$-$weight$)$: $0\mathrm{.}7\frac{k}{f}t$

Distributed Live Load: $1\mathrm{.}3\frac{k}{f}t$

With $f_c=3500$ psi and ASTM A$706$ Grade $60$ reinforcement, find the

following:

a$)$ The weight of the section in $\frac{k}{f}t$

b$)$ The factored design moment $(M_4)$ for the beam per ACl

$318$

c$)$ The factored moment capacity $(M_n)$ of the beam per ACl

$318$

d$)$ Ensure the reinforcement ratio is within the ACl $318$

minimum and maximum limits

e$)$ Is the current beam sufficient for the applied loads?
