Part $($a$)$: $35$ points

Calculate the factored axial loads for the column indicated in red in Figure $1$ using the Load

Combinations handout on Canvas or ACI $318.$ Designate what the controlling demand is in compression

and if applicable in tension as well. The following are the service level loads $($except for wind$)$ that you

calculate for one of the supporting columns. This structiire is not a parking garage.

Please make sure you read through the full Section $5\mathrm{.}3$ in ACI $318$ or the full Load Combinations handout

before starting this problem, specifically Section $5\mathrm{.}3\mathrm{.}5.$

Tributary width for all of the beams shown in Figure $1=20ft$

Dead load $=35$ psf $($each floor$)$

Live load $=80$ psf

Snow load on roof $=25psf$

Roof live load $=20psf$

Rain load on roof $=10$ psf

Wind load on column $=75$kip

Seismic load on column $=80$kip
