Building Construction:
Floor Systems exam
questions and answers
floor
the level base surface of a room or hall upon which one stands
Wood joist system
relatively small joist members closely spaced; joints supported by either
beams or walls; flexible in form and shape
wood plank and beam ststem
larger beams spaced further apart and spanned with structural planking or
decking; beams supported by girders, posts or walls; if underside of
construction is left exposed, it is more difficult to run concealed mechanical
and electrical lines, and the system is less resistant to sound transmission
concrete floor system
pre-cast or cast-in-place; classified according to the type of span
steel joist system
lightgage or open-web joists closely spaced, joists supported by beams or
walls; underside of ceiling may be left exposed or have a ceiling applied;
limited cantilever potential
steel beam and decking
heaving beams spaced further apart and spanned with steel decking or
precast concrete planks, beams supported by girders, columns or walls; an
integral part of a steel skeleton frame system
floor joist
, One of a series of parallel beams of timber, reinforced concrete, or steel used
to support floor and ceiling loads, and supported in turn by larger beams,
girders or bearing walls.
common joist, bridging joist
a joist on which floor boards are laid; neither supports a joist nor is it
supported by another joist
binding joist, binder
A beam which supports the common joists of a wood floor above and the
ceiling joists below; commonly joins two vertical posts.
girder
a large or principal beam used to support concentrated loads at isolated
points along its length
bridging
a brace or a system of braces, placed between joists to stiffen them, to hold
them in place and to help distribute the load
