GLOSSARY OF STRUCTURAL STEELWORK TERMS

AAISC ASB Abbreviation for American Institute of Steel Construction. Abbreviation for Asymmetric Slimdeck Beam. Hot rolled I section beam in which the bottom flange is wider than the top flange. Beam is built into the depth of the slab with the bottom flange supporting the decking, therefore reducing the overall depth of the construction.

ASTM "A" FRAME ABUT ABUTMENT ACCEPTABLE PRODUCT

A structural system utilizing members which when fastened together resemble the letter A. Joining the ends of construction members.Construction intended to resist lateral thrust and vertical load, usually from an arch or bridge. An item named and specified by manufacturers reference meets the specification in all respects and is acceptable to the Engineer. Products listed in various sections are to be used as guides and do not imply exclusion of unlisted manufacturers, models or materials.

ACCEPTABLE WORKMANSHIP ACCEPTANCE TESTING ACCESS TO THE WORK ACCESSIBILITY ACCESSORY ACCIDENTAL LOAD ACCURACY ACOUSTICS ACTUAL COST

Satisfactory to and approved by the reviewing authority associated with the contract. Testing to establish whether a batch of products conforms to the specified requirements. The right of the contractor to ingress and egress, and to occupy the work site as required to reasonably perform the work described in the contract documents. Ability of a space to be entered with ease. A building product which supplements a basic solid panel building such window, light transmitting panel, roof vent, etc. Load that is not specifically foreseen because its occurrence is unlikely but for which an allowance is made in design. Quantitative measure of the degree of conformity with an accepted reference value. The science of sound. In housing, acoustical materials used to keep down noise within a room or to prevent it from passing through walls. The cost actually incurred by the Contractor in the performance of the 'Work.which includes labour, material, actual ownership cost of equipment or invoiced rental rates, and administrative overhead. Achieved size obtained by measurement.Framed construction of triangular cross-section, with legs joined at the top and braced horizontally further down, similar to the letter "A", used for simple one and two storey buildings.

ACTUAL SIZE A-FRAME CONSTRUCTION AGRICULTURAL BUILDING

AIR DUCT ALTERATION ALTERNATE

ALUMINIUM COATED STEEL ANALYSIS ANCHOR BOLTS ANGLE/ANGLE SECTION APEX

A structure designed and constructed to house farm implements, hay grain, poultry, livestock or other agricultural products. Such structures should not include: spaces meant for habitation or to be occupied, spaces in which agricultural products are processed, treated, or the possibility of being as a place of occupancy by the general public. A pipe, usually made of sheet metal, that conducts air to rooms from a central source. Changing or modifying the character or condition of a building, plant or civil engineering works. A Specified item of construction that is set apart by a separate sum. An alternated may or may not be incorporated into the contract sum at the discretion and approval of the owner at the time of contract award. Steel coated with aluminium for corrosion resistance. An investigation of a domain that results in models describing its static and dynamic characteristics. It emphasis question of "what", rather than "how". Bolts used to anchor members to a foundation or other support. Also known as Foundation Bolts. Rolled steel section with a cross - section resembling the letter L, whose legs may be equal or unequal in width. (Also see RSA) 1) The horizontal line formed by opposing sloping sides of a roof running parallel with the building length. 2) The high point/peak of a roof (also known as Ridge).

WHIL Steelwork Glossary APPROVAL DRAWINGS APPROVED CONTRACTOR A Set of drawings that may include framing plans, elevations and sections through the building for approval of the Main Client/Checking Engineer. A Contractor who has demonstrated that they have the expertise, resources, ability and desire to tender for a proposed project. Selection of such contractors in normally a by preselection procedures. Refers to manufacturers, materials, products, systems, or equipment approved by the AIE for use in place of those specified. Curved structural member designed to carry loads between points of support. Abbreviation for Architect. A design professional responsible for developing the aesthetic, functional, performance and overall form of a construction work to meet owner or client requirements by preparing detail drawings, specifications and schedules and ensuring actual construction conforms with those aspects of design.Drawing which shows the appearance of general arrangements, assemblies, component ranges and details of a construction project. Drawing used to record the details of a structure following its completion.

(Allowable Strength Design). Method of proportioning structural components such that the allowable strength equals or exceeds the required strength of the component under the action of the ASD load combinations. A group of mutually dependent and compatible components or subassemblies of components. A drawing which shows the overall configuration and all details required for the fabrication of a complete assembly. Assembly drawings will show all the profile sizes, cutting lengths, drilling of each of the component parts, and how they are to be incorporated into the completed assembly. A number given to each separate part of the building for erection identification. An open court (usually with glass roof) within a building. 2-D detailing software. A manufacturer of cold rolled Purlins and Side Rails. A force tending to elongate or shorten a member. Line around which something rotates or is symmetrically arranged.

BAbbreviation for British Constructional Steelwork Association. Abbreviation for Bought Out. Bought Out lists are issued for special/non standard components required for fabrication/erection. Abbreviation for Bottom of Baseplate Abbreviation for Bill of Quantities. Abbreviation for British Standard. British Standard (Code of Practice) relating to the design of structural steelwork in building construction. Abbreviation for Both Sides. Abbreviation for British Summer Time. UK time between April and October. Indian Time - 4.5 hrs. Abbreviation for Bright Zinc Plated. The process of updating drawings to incorporate comments/corrections made by the checker. Distance from the back (heel) of an angle or channel to a hole positioned in the angle leg or channel flange. Accessible platform projecting or recessed from the external face of a building. A deck projecting from the wall of a building above the ground. A series of balusters or post connected by a rail, generally used adjacent to stairs. A handrailing. Finish board covering the projecting and sloping portion (end rafter) of a gable roof. A plate attached to the bottom of a column, which rests on a foundation or other support, usually secured by anchor bolts. The lowest story of a building, partially or entirely below ground. Secondary members (plates, angles or channels) used to link twin members together.

WHIL Steelwork Glossary BAY BAY WINDOW BEAM BEAM AND COLUMN BEAM SPLICE BEARING PLATE BEARING STRENGTH BENCH MARK The space between the main frames measured normal to the frame. A projection formed by three windows that are joined at obtuse angels. 1) A member, usually horizontal, that is subjected to bending loads.
