Built up Column Below

GIVEN:

Five $-212$#$1$ S$-$P$-$F $($S$)$

Actual size of column $={11\mathrm{.}25}^{\text{'}\text{'}}{7\mathrm{.}50}^{\text{'}\text{'}}$;

$($Solid Column in Problem $7\mathrm{.}23$ was ${11\mathrm{.}50}^{\text{'}\text{'}}{7\mathrm{.}50}^{\text{'}\text{'}})$

Column members will be bolted together

with $2$ rows of bolts in $\frac{1}{2^{\text{'}\text{'}}}$ diameter holes

$L_{by}=8,$ Braced length $($ft$.)$ for buckling about

Column is Pinned $-$ Pinned with no sidesway

$k$:$=1\mathrm{.}0$a Effective Length Factor

FIND: The capacity of the build$-$up column

Members located $24"$ on each side

Top face has sheathing

Bottom face unsupported

Solid blocking at supports and at ends of beam

Check bending stresses

Check shear stress

Calculate deflection from total concentrated load

& compare to L$/360$ for both the span between supports

& the end of the cantilever

Suggest you draw shear & moment diagrams & deflected shape
