$(2)$ A$992$ steel.

${}_{DL}=80$ psf$.$ Not including self weight.

$($a$)(z5\%)$

The beam $$ is

between $(1)-(2)$ and $($A$)-$B$)$

lines.

please chock if

W$1434$ works for the bending and the shear.

Please note the beam $Q$ has a full lateral support provided by the floor deck marked on the plan. $$

$($b$)$ The beam $G$ is along line $(2)$ between $($A$)..$

$(25\%))$ beam $G$ as $W2455$ Please calculate $Mn$ of the beam $G$ as $$2455.$ Need to Consider $C_b$ since the beam $G$ is braced at the mid$-$point.

$($c$)$ extra credit. Check if $M_u{M}_n$ for $(3\%)$ the beam $G.$
