Problem $1$: Design the ground floor exterior stud wall for the two$-$story building with the roof

and floor plans shown in the figure. The floor$-$to$-$floor height is $10ft$ and the wall studs are

spaced at $2ft$ o$.$c$.$ Assume DF$-$L wood species and the design loads shown.

Given: $D=1440lb$;$S=1440lb$;$L=640lb$;$w_{\text{w}\text{i}\text{n}\text{d}}=30l\frac{b}{f}t.$

Check load combination: $D+0\mathrm{.}75(L+S+0\mathrm{.}6W)$

Wall dead load $=10$ pst

Unfactored wind load $(0\mathrm{.}6W)=15$ psf

Floor plan:

Dead load $=20$ pir

Live load $=40$ psf
