A$.$ Prepare a structural steel materials list for the roof$-$framing plan shown in Figure $1.$ The columns are $15$ feet high. The flange width for the $\backslash (\backslash$mathrm$\{$W$\}16\backslash$times $77\backslash )$ is $\backslash (101/4\backslash )$ inches. The properties of the columns are found in Table $1.$

B$.$ Determine the total weight of the joists needed to complete the roof$-$framing plan shown in Figure $2.$ The approximate weights of the joists are found in Table $2.$
