CM $3200$ Statics and Structural Systems

Week $10-1$ Wood Columns $-$ In$-$class Exercise

Determine the adequacy of a $4$X$6$ column given the following information:

a$.$ Wood type: Douglas fir larch No$.1$

b$.$ The actual load on the column is $10,000lb$

c$.$ Columns height is $12\text{'}($unbraced$)$

d$.$ Use load duration $(7$ days$)$ and size factor to adjust wood design values

Would the columns described in question #$1$ be adequate if braced at mid$-$point? Show your calculations.

Determine the adequacy of a stud wall given the following information:

a$.$ The wall supports a floor load of $50$ psf with a tributary width of $20$ ft

b$.$ The studs are $2$X$4$ and spaced at $16"$ on center

c$.$ Wood type: Douglas fir larch south, stud grade

d$.$ The wall is $8$ feet high and braced at $2$ feet $($unbraced length is $6$ ft $)$

e$.$ Use load duration $(10$ years$)$ and size factor to adjust wood design values
