Problem $2$: Roof and floor framing plans are shown on the following sheet for a $2-$story building. The building

is $80$ feet square in plan and has $15-$foot story heights for an overall height of $30$ feet.

The total roof loads are: $50$ psf

The total floor loads are: $160$ psf

Exterior cladding of the building has a total load of $40$ psf

$($Use tributary areas on the exterior surfaces to find the distributed loads, i$.$e$.,$ for the exterior

walls, the top half of the cladding is supported by the beam above, and the bottom half is resting

on the beam below... Just split the wall panels into trib areas like you do with decking!$)$

For beams and girders T$1,$ RB$1,$ FB$1,$ FB$2,$ FB$3,$ FB$4,$ FB$5$

Draw the complete free body diagrams

Draw the shear and moment diagrams $($don$\text{'}$t forget units$)$ and find $V_{\text{M}\text{A}\text{x}}$ and $M_{\text{M}\text{A}\text{x}}$

For columns $C1$ and $C2$ calculate the axial loads at each of the two stories $($remember roof, floor and

exterior loads$).$
