【文章內容簡介】 h member and load is then designated by the letters on opposite sides of it.Braced FrameA frame which resists lateral loads by the use of diagonal bracing, Kbraces, or other system of bracing.BracketA structural support attached to a column or wall on which to fasten another structural member.Bridge CraneA lifting system which has a hoist that moves laterally on a beam or other member which then in turn moves longitudinally on a runway made of beams and rails.BridgingIn general, is a member connected to a joist to brace it from lateral movement. See Horizontal Bridging and Diagonal Bridging.Bridging AnchorAn angle or bent plate attached to a wall where the bridging will be attached or anchored, either by welding or bolting. The ends of all bridging lines terminating at walls or beams shall be anchored thereto.Bridging ClipA small piece of angle or plate with a hole or slot that is welded to the top and bottom chord angles so that bridging may be attached.Bridging DiagramA diagram of the profile of a joist used to show the number and location of the rows of bridging.Brittle FractureThe tearing or splitting of a member with little or no prior ductile deformation.BTU (British Thermal Unit)The amount of heat required to raise the temperature of one pound of water by one degree farenheit.Buckling LoadThe load at which a straight member under pression transfers to a deflected position.BuildingAny structure used for support or for shelter.Building CodeRegulations established by a recognized agency describing design loads, procedures, quality of materials, and construction details for buildings for the protection of the public.Building DesignerA registered architect or registered engineer who is responsible for the design of a structure. See Specifying Professional.Building OfficialThe officer or other authority which has the duty of administration and enforcement of a building code.BuiltUp RoofA type of roof posed of two or more layers of alternating felt, tar and asphalt.BuiltUp SectionA structural member made up from individual flat plates welded together or any structural metal elements that are welded or bolted together.Butt PlateThe end plate of a structural member usually used to rest or butt against a like plate of another member in forming a connection. [C]C ShapesA hot rolled shape called an American Standard Channel with symbol C.C SectionA structural member coldformed from sheet steel in the shape of a block C which can be used by itself or back to back with another C Section.CADAbbreviation for ComputerAided Drafting.CalipersA mechanical instrument usually having a pair of pivoted legs adjustable to any distance and used to measure thichness, distances between surfaces, and any internal or external diameter which is inaccessible with a scale.CamberCamber is an upward curvature of the chords of a joist or joist girder induced during shop fabrication to pensate for deflection due to loading conditions. Note, this is in addition to the pitch of the top chord.CanopyA projecting member that is supported at one end only.Cant StripA deck accessory which is a short piece of gage steel used at 45 degrees where a wall or parapet meets the end of deck.Canted SeatA seat which is sloped perpendicular to the member which most joist manufactures do not do. Usually the steel contractor furnishes a bent plate shim to provide level bearing for the seat.CantileverThe part of a member that extends freely over a support which is not supported at its end.Cap PlateA steel plate welded to the top of a column which a joist, joist girder, or other structural member can bear on.CatwalkSuspended structural framing used to provide access to and between areas below a roof and above a floor.Ceiling ExtensionIs similar to a bottom chord extension except that only one angle of the joist bottom chord is extended from the first bottom chord panel point towards the end of the joist.Centerline Span (or CentertoCenter)A theoretical span definition which is the distance between the actual centerlines of a beam, column, joist, or joist girder.CentroidThe point in a member at the intersection of two perpendicular axes so located that the moments of the areas on opposite sides of an axis about that axis is zero.Certified WelderA welder who has been certified by a petent experienced welding inspector or a recognized testing facility in the field of welding. The welder must be certified to make certain welds under qualified procedures. The welder must be qualified for each position, type weld, electrode, and thickness of base metal that is to be welded in the shop or field.Change OrderA written document which modifies the plans, specifications, or price of a construction contract.ChannelA hot rolled structural shape the looks like [. There are American Standard Channels designated by (C) and Miscellaneous Channels designated by (MC).ChordThe two angle top or bottom member of a joist or joist girder, usually with a gap between the angles.CladdingThe exterior covering of the structural members of a building.Clear SpanThe actual clear distance or opening between supports for a structural member, ., the distance between walls or the distance between the edges of flanges of beams.ClevisA Ushaped yoke with internal threads in one end which can be attached to a threaded rod and the other end a connection with a hole used for a pin or bolt attchment.Clip AngleA structural angle which attaches to the side of a wall, column, beam, etc. where a joist, joist girder, or other structural member bears.Closure StripA floor deck accessory made of gage metal which is placed over the ends of deck so that concrete cannot run out of the flutes of the deck.Coefficient of (Linear) ExpansionThe change in length, per unit, for a change of one degree of temperature.ColdFormedThe p
