Determine the reaction forces for beams $B-1,B-2,$ and $B-3.$

Live load $=60$ psf

Dead load: $(1)$ Slab $=50$ psf$,(2)$ Deck $=5$ psf$,(3)$ Mechanical equipment $=13psf,(4)$ Suspended ceiling $=8$ psf$,(5)$ Beam $=25l\frac{b}{f}t,(6)$ Girder $=35l\frac{b}{f}t$

Beam and Girder spacing: : $(1)L1=12ft,(2)L2=12ft,(3)L3=10ft$

Please round to the nearest one.

Reaction force for Beam B$-1($one side only$)=$ lbs

Reaction force for Beam B$-2($one side only$)=$ lbs

Reaction force for Beam B$-3($open side$)=$ lbs

Reaction force for Beam B$-3($Girder G$-1$ side$)=$ lbs
