Question $1-$

design rectangular sections for the beams, loads, and values given. Beam weights are not included in the given loads. Show

sketches of beam cross sections, including bar sizes, arrangement, and spacing. Assume concrete weighs $150l\frac{b}{f}t.$

assume the beam weight as $0\mathrm{.}5\frac{k}{f}t$ and check if this is correct or not. Use $h=d+2\mathrm{.}5in.$

$f_y()=60,000$

$fc()=4000$

Span I $(ft)=32$

$wD$ not incl. beam $wt(\frac{k}{f}t)=2$

$wL(\frac{k}{f}t)=1\mathrm{.}8$

${}^{**}=\frac{1}{2}ps$
