Consider the floor plan shown below.

$3\mathrm{.}1$ Compute the tributary areas for $(a)$ floor beam B$1,($b$)$ floor beam B$2,($c$)$ girder G$1,(d)$ girder G$2($e$)$ corner column $C1,$ and $(f)$ interior column $C2.$

$3\mathrm{.}2$ Compute the tributary width for $($a$)$ floor beam B$1,($b$)$ floor beam B$2.$

$3\mathrm{.}3$ Draw a free$-$body diagram representing the type of load carried by $(a)$ floor beam $B1,(b)$ floor beam $B2,(c)$ girder G$1,(d)$ girder G$2($e$)$ corner column C$1,$ and $(f)$ interior column C$2.$

$3\mathrm{.}4$ The uniformly distributed live load on the floor plan in Figure P$2\mathrm{.}4$ is $60l\frac{b}{f}{t}^2.$ Establish the loading for members $(a)$ floor beam B$1,(b)$ floor beam $B2,(c)$ girder $G1,$ and $(d)$ girder G$2.$

$3\mathrm{.}5$ An elevation of the building associated with the floor plan is shown in below. Assume a live load of $60l\frac{b}{f}{t}^2$ on all floors and roof. Calculate the axial forces produced by the live load in column $C1$ in the third and first stories.
