From the glossary of Detailing For Steel Construction Second Edition
A document issued to make changes in the material already ordered.
A common structural steel shape the cross section of which is similar to that of a S shape except that the flanges are on only one side of the web.
To verify the accuracy of all information relating to sketches of structural members and their details, dimensions, notes and material on a drawing, advance bill or any other document originated within the detailing group.
A person in the detailing group who, by reason of experience and ability, has advanced successfully from a beginning steel detailer to a position with more responsibility.
A steel plate with raised ribs or a raised pattern used for a walking surface.
Checkered plate or Raised pattern floor plate or floor plate
To cut off projecting parts, as with a pneumatic chisel.
The main top or bottom member, or line of members, in a truss.
The length of a span from face to face of supports
A space left between members, or parts of members, to allow for inaccuracies in cutting and to facilitate placing them in position
A forging used to connect a specialized rod to a plate or angle. The forging is arranged to thread on the end of the rod and the plate is inserted between two flattened ends through which a pin is passed.
A small connection angle. Also, to remove the corner of a plate or angle at 45 degrees to clear a beam fillet or a fillet weld.
Clip or Snipe
A relatively long vertical, or near-vertical, structural member whose primary function is to carry compression loads parallel to its longitudinal axis. It is the principal vertical member in a building.
The base plate, slab or pedestal upon which a column stands, together with any connecting angles or plates.
A drawing upon which is summarized information regarding the composition and lengths of different sections of the columns in a tier building.
One of two or more parts into which a force or stress may be resolved. The force or stress is the resultant of these.
A steel beam structurally connected to a concrete slab so that the beam and slab respond to loads as a unit.
A member in which the principal stresses tend to compress or shorten the member.
The stress induced by axial forces on a member directed toward each other. They tend to compress or shorten the member.
A load that is assumed to act at one point
A mixture of cement, water, sand and coarse aggregate, which hardens in forms to make structural members, slabs, walls, etc.
Combination of plates, angles, bolts and/or welds used to transmit forces between two or more members. Categorized by the type of force transferred (moment, shear, end reaction, etc.)
An angle or plate for connecting members
Connection angle or Connection plate
An agent retained by the owner to represent the interests of the owner in the proper execution of the project.
A beam girder that spans continuously over one or more intermediate supports.
Continuous beam or Continuous girder
A change in the direction of bending in any member.
A type of contract wherein payment is based on the actual cost of material and all labor plus a percentage of these costs.
Cost plus contract
A cylindrical steel pin held in place by a split steel key placed through a hole in the pin.
To ream a hole to receive the conical head of a bolt or screw so that the head will not project beyond the face of the part connected.
A plate attached to the flanges of a beam girder or column to increase the area of the cross section.
A hoisting machine arranged to move heavy loads both vertically and horizontally. An overhead traveling machine usually is used in mill buildings, being supported by longitudinal girders on opposite sides of the building.
A diagram made to show a crane manufacturer the principal column, truss and kneebrace dimensions so that the crane can perform.
A girder that supports one of the rails upon which a traveling crane runs.
Crane runway girder
A cast or built-up block attached to a crane runway girder at the end of a runway to stop a crane.
Bracing with two intersecting diagonals forming the shape of an X.
A transverse section. Also, a view representing the appearance of a structure or member where cut by an imaginary section plane.
A term used by some fabricators to describe the removal of a portion of a steel piece.
The comparatively constant static load on a structure due to its weight, as distinguished from the live or moving load, wind load, or seismic load.
A movement at right angles to either principal axis of a member. Also, the linear measurement of such movement.
One of many types of reinforcing bars which are rolled with projections to increase the bond to the surrounding concrete
A hoisting machine so pivoted that a load may be swung horizontally. Two types are a Guyed and Stiff-leg.
A type of contract in which an owner retains a general contractor to assume responsibility for the design and construction of the structure.
A drawing prepared by the owner's designated representative for design to show the dimensions, configuration, sizes, connections and other aspects of the structure.
Resistance (force, moment, stress, as appropriate) provided by a structural element or connection. In LRFD the product of the nominal strencth and the resistance factor.
The owner's designated representative for design
To make shop and erection drawings. Also, a connection or other minor part of a member in contrast to the main member.
An organization of structural steel detailers and checkers whose purpose is to supply a fabricator with accurately prepared shop drawings.
One who manages a detailing group, and whose responsibilities include becoming familiar with the project plans and specifications and scheduling the detailing work to meet the fabricator's schedule.
To represent on a drawing a bent or curved piece as if it were flattened into place
Inclined structural members carrying primarily axial load employed to enable a structural frame to act as a truss to resist horizontal loads.
A drawing in which each member usually is represented by a single line, as in an erection drawing or a load diagram.
