Construction Structural Steel Detailing

From the glossary of Detailing For Steel Construction Second Edition
Show Answers:

  1. An element that stabilizes a system or elements of a system, primarily through shear; e.g. floor slabs and shear walls. Also, a stiffening plate or similar part placed between the webs of a member, or from one member to another.
  2. A steel form used in forging or cutting any piece.
  3. A linear measurement indicated on a drawing upon a dimension line to show its extent and significance
  4. A washer-type element inserted under the bolt head or hardened washer, having several small arches, which deform in a controlled manner when subjected to load. See the RCSC Specification for further information.
    Direct tension indicators
  5. The tendency to shear, or the resistance to shear, a single element or group of elements on two planes.
    Double shear
  6. Making working drawings, usually including design of the details.
  7. A member of the detailing group who plans and organizes work assignments and supervises a group of structural steel detailers and checkers in the work of the group.
    Drafting project leader
  8. The tension induced in diagonals of bracing systems to insure initial tightness
  9. Lateral deflection of a building
  10. A tapered pin used in assembling members in the shop or during erection. It is driven into the connection holes to bring them into alignment to permit installation of permanent bolts.
    Drift pin
  11. To make a hole by means of a rotating cutting tool or bit.
  12. A characteristic of steel in which, when steel is under load and stressed beyond its yield strength, strain increases disproportionately greater than stress, resulting in permanent distortion. When the load is released, the steel does not revert to its original shape.
  13. A longitudinal member between the tops of columns at the eaves of a building.
    Eave strut
  14. A connection in which the line of action of a resultant load does not pass through the centroid of a group of connecting bolts or welds.
    Eccentric connection
  15. The perpendicular distance from a resultant force to some other point or line.
  16. The perpendicular distance from the center of a hole to the edge of the piece that contains it.
    Edge distance
  17. The distance from end to end of a fillet weld measured parallel to its root line. For curved fillet welds the effective length is measured along the centerline of the throat.
    Effective weld length
  18. A property of steel in which steel will return to its original shape following deformation by an externally applied force not exceeding the yield strength.
  19. The vertical distance from a reference surface or datum. Also, a drawing or view that represents the projection of a structure or member upon a vertical plane.
  20. A steel component cast into concrete and used to transmit externally applied loads to the concrete by means of bearing, shear, bond, friction or any combination thereof.
  21. The minimum distance from the center of a bolt to the nearest projecting part that might interfere with the use of the wrench used to tighten the bolt.
    Entering and tightening clearance
  22. The forces that act upon a body are said to be in equilibrium when they so balance each other that the body has no tendency to move.
  23. The assembling and connecting of the different members of a structure in their proper positions at the job site.
  24. Bolts used during erection to hold members in position until field welds are placed or permanent field bolts are installed.
    Erection bolts
  25. Clearance between members provided to facilitate erection
    Erection clearance.
  26. A drawing consisting of line diagrams representing framing in a plan, elevation, section, etc. to which are added principal dimensions, erection marks, notes and, when required, enlarged details, thus providing the erector with sufficient information to place the members in the structure. These drawings do not normally show the erection scheme, schedule, rigging devices, temporary supports, safety devices, etc.
    Erection drawing
  27. An identifying mark that aids the erector in properly placing a member.
    Erection mark or Shipping mark
  28. A seat angle bolted or welded to a supporting member to support a beam, girder or similar member temporarily during erection.
    Erection seat
  29. The party responsible for the erection of the structural steel. Also, a term used to identify any or all the workers performing erection activities.
  30. To compile the quantities, weights and costs of a structure as a basis for bidding.
  31. A bolt for attaching steelwork to a masonry/concrete wall or concrete slab. The bolt is surrounded by a split sleeve that expands as the bolt is tightened in a hole drilled into the masonry or concrete.
    Expansion bolt
  32. Cumulative dimensions from a given point, such as the left end of a beam or the finished bottom of a column shaft, used to locate several connections with the same position of a measuring tape.
    Extension dimensions
  33. The costs incurred for performing work beyond the scope of work originally contracted to perform.
  34. The shop work required to convert raw material into complete structural members or the work done in a structural shop.
  35. The party responsible for furnishing fabricated structural steel.
  36. To plane or smooth s surface. Also, the exterior plane surface of any solid.
  37. The product of the nominal load and a load factor - or a combination of such products.
    Factored load
  38. A temporary system of steel and/or timber columns, beams and bracing for supporting a structure during erection or demolition.
  39. Generic term for welds, bolts or other connecting devices.
  40. A fracture phenomenon resulting from a fluctuating stress cycle.
  41. Contact surface between two plies in a connection.
    Faying surface
  42. A term applied to the work done on parts of a structure at or near the job site as opposed to work done in the shop. Also, used interchangeably with the terms job site or site.
  43. A partial checking of the drawings of a structure to ensure the proper connection of the members in the field.
    Field check
  44. A connection of different members made by the erector.
    Field connection
  45. A bolt installed or weld placed in the field as distinguished from a shop bolt or weld.
    Field bolt or field weld
  46. A list of field bolts required to make the necessary field connections in a structure.
    Field bolt summary
  47. A drawing showing sketches and details of connections to existing structures. Also, it may be used as a preliminary drawing to list field measurements, which will determine the length and connection details of new members connecting to an existing structure.
    Field work drawing
  48. A plate or combination of plates used to fill the space between two surfaces.
  49. The additional metal that forms the curve at the juncion of the flange and web of a rolled shape.
  50. A weld having a theoretically triangular cross-section joining two surfaces that abut perpendicular to each other.
    Fillet weld
