Show me the steps to solve Problem $1[$Required$]$: The following is a floor plan for a $2304$ sq ft reading room in a library $(60$ psf $).$ The concrete columns are $25$ ft in length and have an elastic modulus $($E$)$ of $3370$ ksi $.$ The concrete slab $(=150pcf)$ is $6$ inches thick. The beams which are directly supported by the girders are W$12$x$87$ steel sections and the girders are W$18$x$86$ steel sections.

Column B$2.$ Calculate and draw the unfactored loading on one of the interior beams $($include the selfweight of the beam$).$ Keep the live load and dead loads separate on your Free Body Diagram.

$($b$)$ Calculate and draw the unfactored loading on girder A$2$ B$2($include the self$-$weight of the

beams$).$ Keep the live load and dead loads separate on your Free Body Diagram.

$($c$)$ Draw the shear and bending moment diagram of the interior beam in $($a$)$ and the girder in $($b$)$

$($assuming simply supported end conditions$).$ Label moment and shear at the ends and midspan

of the beam. For this case you may add the live and dead loads together.

$($d$)$ Calculate the unfactored loading demand on column B$2($neglect the self$-$weight of the

columns$).$ Keep the total dead load and live load separated in your calculations.

$($e$)$ Will column C buckle if the ends are pinned $($k$=1,0)?$
