$(3)$ The columns for the frames shown in the accompanying illustration are braced top

and bottom against sidesway out of the plane of the frame so that $K=1\mathrm{.}0$ in that

direction. Sidesway is possible in the plane of the frame. Design the interior column,

$2=$

ASD and the exterior columns with $K$ as determined from the

ablipment chart Tse $=50$ksi and a W$14$ section.

$P_D=200k,P_D=400k,P_D=200k$

$P_L=500k,P_L=1000k,P_L=500k$
