The building section associated with the floor plan is shown in the figure. Assume a live load of $55l\frac{b}{f}{t}^2$ on all three floors $($Treat the

third floor as a floor and not as a roof$).$ Calculate the axial forces produced by the live load in column C$3$ in the third and first stories.

Consider any live load reduction if permitted by the ASCE standard. Ignore the reduction in load allowed by the increasing tributary

area as you move down the column.

The axial force produced by the live load in column $C_3$ in the third story is

kips.

The axial force produced by the live load in column $C3$ in the first story is

kips.
