  1. SSPC
    The Society for Protective Coatings or the Steel Structures Painting Council
  2. A wooden strip bolted to a steel beam or similar member to which strip planking or sheathing may be nailed or spiked.
    Spiking piece
  3. A small round or square rod bent in the form of a helix, used in reinforced-concrete columns to prevent the longitudinal reinforcing bars from spreading.
  4. The connection between two structural elements joined at their ends to form a single, longer element.
  5. A beam that is split to form a structural tee or bracket. Also, a beam split part way with one flange bent out to permit welding a plate in the web for strengthening the joint for rigid-frame construction.
    Split beam
  6. The placement of a spot of paint on the faying surface of a single-angle, single-plate or tee. It is one of several methods used to alert the erector as to which side to connect a supported member.
  7. Bolts which alternate on two parallel bolt lines.
    Staggered bolts
  8. The product of an area times the distance from an axis to the center of gravity of the area.
    Statical moment
  9. A modified form of iron used in construction.
  10. And individual who uses contract documents to make detailed working drawings for each piece of steel to be furnished by a fabricator and erected by an erector.
    Steel Detailer
  11. A member, usually an angle or plate, attached to a plate or to the web of a beam, girder or column. Its purpose is to distribute load, transfer shear, or prevent buckling of the member to which it is attached.
  12. Bolts used to hold the angles of a multi-shape member together at intervals. If the elements are seperated by connection (gusset) plates, a stitch filler is placed between them at each stitch bolt to maintain a constant space.
    Stitch bolts
  13. The deformation in a member caused by external forces. Measured in linear units.
  14. Limiting condition affecting the safety of the structure, in which the ultimate load-carrying capacity is reached.
    Strength limit state
  15. Force per unit area, such as pounds per square inch/foot.
  16. Localized stress considerably higher than average as a result of abrupt changes in geometry or localized loading.
    Stress concentration
  17. Shim consisting of a narrow piece of structural steel punched with round holes.
    Strip shim
  18. The placement of a stripe of paint on the faying surface of a single-angle, single-plate or tee. It is one of several methods used to alert the erector as to which side to connect a supported member.
  19. The major principal axis of a cross section denoted as the X-X axis.
    Strong axis
  20. Documents prepared by the designer (plans, design details and job specifications). These documents define the responsibilities of the parties involved in bidding, purchasing, supplying and erecting structural steel.
    Structural design documents
  21. The preperation of the working drawings for the members in a structure.
    Structural drafting
  22. A shop where rolled steel shapes and plates are punched, cut, bolted, welded and otherwise prepared for erection in a steel structure.
    Structural shop
  23. A T-shaped member made by cutting a W, M or S shape in two along the length of its web.
    Structural tee
  24. A comparatively light compression member, usually with no intermediate connections.
  25. To punch a hole to a smaller diameter than required, that will be reamed after parts are assembled.
  26. The concrete piers or foundation for a structure.
  27. The main part of the structure above the concrete foundation or sub-structure.
  28. Bracing in a vertical plane as between the roof trusses of a mill building.
    Sway bracing
  29. A comparatively flat horizontal curve in a beam or girder induced through cold bending or by the application of heat.
  30. A type of anchor rod threaded at one end for a nut and having depressions in the remaining length of shank to furnish bond when embedded in masonry or concrete.
    Swedge bolt
  31. A full-size pattern or guide (made of wood, cardboard or steel) used to locate punched or drilled holes and cuts or bends to be made in the steel.
  32. The condition of a material loaded in such a way that the load tends to stretch the material in the direction of its length
  33. An alternative design type of fastener with a splined end extending beyond the threaded portion of the bolt. The bolt is installed using a special wrench to remove the splined end when the proper pretension is induced in the bolt.
    Tension-control (twist-off) bolt
  34. A member in which the principal stresses tend to lengthen the member.
    Tension member
  35. The maximum tensile stress that a material is capable of sustaining.
    Tensile strenth
  36. In a fillet weld the distance from the root to the face of the weld.
  37. A light tension member, such as the diagonal in a bracing system.
  38. A plate for holding the component parts of a member at the proper distance apart. Generally used in tension members.
    Tie plate
  39. A term relating to a length of column supporting one, two or three floors of steel.
  40. Termination point of fillet weld or of rolled section fillet.
    Toe of the fillet
  41. A connection angle used at the top of a beam in conjunction with a seat angle on a column or in a girder web.
    Top angle
  42. The action of applied load(s) that tend to twist a member.
  43. Paper specially treated to make it transparent so that copies can be made of drawings on it.
    Tracing paper
  44. A crane mounted on a mobile truck.
    Truck crane
  45. A framed structure that acts like a beam. The principal members usually form a series of triangles and each member primarily is subjected to axial stress/loads only.
  46. Similar to a sleeve nut except that a transverse opening is provided at the center for the insertion of a crowbar for turning the turnbuckle.
  47. Procedure whereby the specified pretension in high-strength bolts is controlled by rotation of the nut a predetermined amount after the snug-tightened condition has been achieved.
    Turn-of-nut method
  48. A rod bent in the shape of the letter U with each end threaded for nuts.
  49. A groove melted into the base metal adjacent to the weld toe or weld root and left unfilled by weld metal
  50. The amount of decrease in the actual length of a structural shape over the theoretical dimension indicated on the drawing or advance bill. Also, the amount of decrease in the actual cross section dimensions from those published in ASTM A6, A500 or A53 (as summarized in the AISC Manual of Steel Construction)
