$5.$ Given: the floor system and unfactored loads & weights shown.

Complete parts $($a$),($b$)$ & $($c$)$ as stated below and on the next pages.

The loads on the floor deck are:

Dead Load $=30$ psf

Live Load $=50psf$

Member self$-$weights:

G$1$ & G$3$: $80$ plf

G$2$: $60$ plf

All others: $45$ plf

Consider the standard load combinations of: $1\mathrm{.}4$ D

$1\mathrm{.}2D+1\mathrm{.}6L$

$($a$.)$ Construct the design loading model for member B$2,$ B$5,$ and G$2$

Be sure to include the magnitudes of the reactions in your model.
