Which term is the horizontal member that supports a floor or ceiling and spans between supports?

• A. Joist
• B. Beam
• C. Girder
• D. Filler beam

Answer: (A)

The term describes the horizontal framing member that carries the floor or ceiling load and spans between supports. This is the joist, which runs from bearing wall to bearing wall or beam and provides the primary structural support for the floor or ceiling, with the subfloor placed on top. Beams carry loads from multiple joists and span between supports themselves, while girders are larger members supporting beams, and a filler beam isn’t the typical term for standard floor framing. So the correct choice is the joist.
