"Values listed are for reference in determining design use values subject to various modifications. See Table $5\mathrm{.}2$ for size adjustment factors for dimeasion lumber

$(2-4$ in$.$ thick$).$ For design purposes, values are subject to various modifications.J$\mathrm{.}5$ Combined Axial and Bending loads: A WLF exterior wall is made with $2$x$6$ studs and are each exactly $12\text{'}$ tall. Use Doug Fir$-$Larch No $1$ grade. The wind load on the wall is $24$psf on the wall surface, studs are $16"$ o$.$c$.,$ and the gravity load on the wall is $500$ #$/$ft of wall length. The exterior sheathing is nailed at $10"$o$.$c at each stud. Investigate the studs for combined action of compression plus bending using the ASD method.
