Problem $5$ : Design rectangular sections for the beam, load, and $p$ values given.

Factor the loads shown in the figure below for using the LRFD method

Then, analyze your deurgned beam $($check Beam Belf Weight, As$,$ bmin, $$ min & ma

Check if the beam is adequate for the applied moment $($ $$Mn>)$

Sketch the beam including stirrup

Given

a$)F_4=60,000$ psi and $f^{\text{'}}c=4,000$ posi.

b$)$ Aosume the Beam weight is $1\mathrm{.}2\frac{k}{f}t$ and adds to the given Dead Load

on the beam $($figure below$)$

c$)p=0\mathrm{.}012$

d$)=0\mathrm{.}9$

d$)b=28in.$

e$)$ Edge distance $=3\mathrm{.}5in,$ find $h?$

f$)$ Ube # II bar

g$)$ To check the beam self$-$werght, use $150l\frac{b}{f}{t}^3$ for reinforce concrete weight
