brace Rods: Rods or cables used in roof and
walls to transfer loads such as wind loads, and
seismic and crane thrusts to the foundation . (Also
often used to plumb buildings but not designed to
replace erection cables .)
bracing: Rods, angles or cables used in the plane
of the roof and walls to transfer loads, such as wind,
seismic and crane thrusts to the foundation .
bracket: A structural support projecting from a
wall or column on which to fasten another structural
member . Examples are canopy brackets, lean-to
brackets, and crane runway brackets .
bridge crane: A load-lifting system consisting of a
hoist that moves laterally on a beam, girder, or bridge
that in turn moves longitudinally on a runway made
of beams and rails . Loads can be moved to any
point within a rectangle formed by the bridge span
and runway length .
builder/contractor: A general contractor or
sub-contractor responsible for providing and erecting
metal building systems .
building code: Regulations established by
a recognized agency describing design loads,
procedures, and construction details for structures .
Usually applying to designated political jurisdiction
(city, county, state, etc .)
built-Up section: A structural member, usually
an “I” section, made from individual flat plates
welded together .
butt Plate: The end plate of a structural member
usually used to rest against a like plate of another
member in forming a connection . Sometimes called
a split plate or bolted end plate .
“c” section: A member formed from steel sheet
in the shape of a block “C”, that may be used either
singularly or back to back .
camber: A predetermined curvature designed
into a structural member to offset the anticipated
deflection when loads are applied .
canopy: Any overhanging or projecting roof
structure with the extreme end usually unsupported .
cantilever: A projecting beam that is supported
and restrained at one end only .
capillary action: That action which causes
movement of liquids when in contact with two
adjacent surfaces such as panel sidelaps .
cap Plate: A plate located at the top of a
column or end of a beam for capping the exposed
end of a member .
caulk: To seal and make weather tight the joints,
seams, or voids by filling with a waterproofing
compound or material .
channel – Hot Rolled: A member formed while
in a semi-molten state at the steel mill to a shape
having standard dimensions and properties .
clip: A plate or angle used to fasten two or more
members together .
closure strip: A resilient strip, formed to the
contour of ribbed panels used to close openings
created by joining metal panels and flashing .
cold forming: The process of using press brakes
or rolling mills to shape steel into desired cross
sections at room temperature .
collateral load: All specified additional dead
loads other than the metal building framing, such
as sprinklers, mechanical and electrical systems,
and ceilings .
column: A primary member used in a vertical
position on a building to transfer loads from main
roof beams, trusses, or rafters to the foundation .
continuity: The terminology given to a structural
member, as if there were no connections .
contractor: See “Builder”.
coverings: The exterior roof and wall covering for
a metal building system .
crane: A machine designed to move material by
means of a hoist .
crane Rail: A track supporting and guiding the
wheels of a bridge crane or trolley system .
