Using the floor plan and loading information, Design column Cl from the foundation to the roof using W$10$ steel sections. Ignore LL reduction. Building is a $7-$story building: $6$ framed above ground floors and a roof.

a$.$ Splice the column every floor.

b$.$ Splice the column every other floor $($starting with $2$ stories at the bottom$).$

c$.$ Compare the contrast bullet $1$ and bullet $2$ in terms of differences to the designs

$LL=60psf,DL=75psf(includess.w.)$

$Lr=20psf,DL=25psf(includess.w.)$

Floor$-$to$-$floor height: ${15}^{\text{'}}-9"$ except first flonrwhich ic ${90}^{\text{'}}-6^{\text{'}\text{'}}$
