For the floor framing plan below, assume a floor dead load of $10psf$ and a live load of $40psf.$ For each of beams B$1,$ B$2,$ B$3,$ and girders G$1,$ G$2,$ G$3$:

a$.$ determine the loading diagram $($all distributed and$/$or point loads$)$ for the member

b$.$ starting with the beams, solve for the support reactions at the ends, assuming all members are simply supported.

Finally, trace the loads through the structure to determine all column loads $($columns C$1$ through C$6).$ Tabulate your answers for clarity.
