$1)$ Will column C buckle if the ends are pinned $(k=1\mathrm{.}0)?$

$2)$ If the deflection limits set forth by the ASCE building code are $[in]\frac{L[in]}{360},$ does the

interior beam in $($a$)$ meet this requirement $($note: $E_{\text{s}\text{t}\text{e}\text{c}\text{l}}=29,000$ksi,$I_{x,\text{b}\text{e}\text{a}\text{m}}=740i{n}^4)$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.
