Anchor Bolt Plan - Anchor Bolt Plans (a plan view) show the size, location and projection of all anchor bolts for the components of the metal building system, the length and width of the foundation (which may vary from the nominal size of the metal building system) and column reaction (magnitude and direction). The maximum base plate dimensions may also be shown. Approval Plans - Approval plans may include framing plans, elevations, and sections through the building for approval of the buyer. ASCE - American Society of Civil Engineers. Astragal - A closure between the two leaves of a double swing or double slide door to close the junction. Automatic Welding - A welding procedure utilizing a machine to make a weld. Auxiliary Loads - All dynamic live loads required by the contract document, such as cranes and material handling systems. Axial Force - A force tending to elongate and shorten a member. B Base Angle - An angle secured to a wall or foundation used to attach the base of the wall paneling. Base Plate - A plate attached to the base of a column which rests on a foundation or other support, usually secured by anchor bolts. Bay - The space between the primary frames measured parallel to the ridge. Beam - A member, usually horizontal, that is subjected to bending loads. There are three types; simple, continuous and cantilever. Beam and Column - A structural system consisting of a series of rafter beams supported by columns. Often used as the end frame of a metal building. Bearing End Frame - See "Beam and Column". Bearing Plate - A steel plate that is set on the top of a masonry support on which a beam or purlin can rest. Bent - The main member of a structural system. Bill of Materials - A list of items or components used for fabrication, shipping, receiving, and accounting purposes. Bird Screen - Wire mesh used to prevent birds from entering the building through ventilators and louvers. Blind Rivet - A small headed pin with expandable shank for joining light gage metal. Typically used to attach flashing, gutter, etc.. BOCA - Building Officials and Code Administrators International, Inc.. Brace Rods, Angles, and Cables - Braces 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). 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 which moves laterally on a beam, girder, or bridge which 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. Bridging - Structural member used to give weak axis stability to bar joists. British Thermal Unit (BTU) - That amount of heat required to raise the temperature of one pound (2.2 kg) of water by 1^o F (0.56^oC.). 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.). Building Line - See "Steel Line". Built-Up Roofing - A roof covering made of alternating layers of tar and asphaltic materials. Built-Up Sections - 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 splice plate or bolted end plate. C "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 - Curvature of a flexural member in the plane of its web before loading. Canopy - 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 side laps. Cap Plate - A plate located at the top of a column or end of a beam for capping the exposed end of the member. Caulk - To seal and make weathertight joints, seams, or voids by filling with a waterproofing compound or material. Channel-Hot-Rolled - A "C" shaped 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 and used to close openings created by metal panels joining other components. Cold Forming - The process of using press brakes or rolling mills to shape steel into desired cross sections at room temperature. Collateral Load - All additional dead loads required by the contract documents other than the weight of the metal building system, such as sprinklers, mechanical and electrical systems, and ceilings. Column - A main member used in a vertical position on a building to transfer loads from main roof beams, trusses, or rafters to the foundation. Component - A part of a metal building system. Continuity - The terminology given to a structural system denoting the transfer of loads and stresses from member to member as if there were no connections. Contract Documents - The documents which define the responsibilities of the parties involved in the sale, supply, and erection of a metal building system. Such documents normally consist of a contract and specification. Plans may be included. Corner Post - An end wall column located at the corner of the building. Covering - The exterior metal roof and wall paneling of a metal building system. Crane - A machine designed to move materials by means of a hoist. Crane Rail - A track supporting and guiding the wheels of a bridge crane of trolley system. Crane Runway Beam - The member that supports a crane rail and is supported by columns or rafters depending on the type of crane system. On underhung bridge cranes, runway beam also acts as crane rail. Curb - A raised edge on a concrete floor slab or skylight. Curtain Wall - Perimeter wall panels which carry only their own weight and wind load.
