Problem $3$: For the floor framing plan in problem #$2$ above, assume the structure is $6$ stories

tall, with the first story being $22$ ft tall, the second through fifth stories $16$ ft tall, and the sixth

story $24$ ft tall. Assume that the floor dead load is $60$psf and live load is $70$psf$,$ and the roof

loads are $30$psf dead and $30$psf live. Design the lightest$-$weight interior column $($C$5),$ assuming

there are to be three sections of two$-$story spans $(1-2,3-4$ and $5-6).$ Draw a story$-$by$-$story axial

force diagram, and use the sizing tables below:
