Partial floor framing plan

A steel$-$framed floor for an office building was designed to support a load condition as follows: Loads:

Live Load $=50$ psf

Dead loads:

Concrete $=150$ pcf

Steel Decking $=5$ psf

Mechanical Equipment $=10$ psf

Suspended Ceiling $=5$ psf

Steel beams $=25$ lb$/$ft

Steel Girders $=35$ lb$/$ft

Using appropriate FBDs$,$ determine the reaction forces for the following:
