Show Answers:

  1. A round rod.
  2. A rolled structural steel shape the cross section of which resembles the letter I and characterized by narrow, tapered flanges and relatively thick webs.
    S beam
  3. A vertical or inclined tie rod used to reduce the sagging of a girt or purlin.
    Sag rod
  4. A roof arrangement providing for sky light without direct sunlight. The vertical or steeper slopes are glazed while the smaller slopes toward the sun are covered with roofing material
    Sawtooth roof
  5. A flat or triangular measuring stick used in potting a drawing in proportion to the thing represented. Also, this proportion.
  6. Angle bolted or welded to one member such that its outstanding leg is, or nearly is, horizontal to support the end of another member.
    Seat angle
  7. A cut across a member or structure made by an imaginary section.
  8. Fine sloping lines used to shade an area cut by a section plane. In current practice these lines are omitted in sectional views on structural steel shop drawings.
    Section lines
  9. The projection of one segment of a member or structure upon a section plane.
    Sectional view
  10. A plate or piece of pipe placed between the webs of beams to keep them a fixed distance apart.
  11. SER
    Structural Engineer of Record
  12. The limiting condition affecting the ability of a structure to preserve its appearance, maintainability, durability, or the comfort of its occupants or function of machinery under normal usage.
    Servicability limit state
  13. In detailing beams and girders, the distance from the extreme end of the member to a major reference line, such as the centerline of the supporting beam, girder or column.
  14. The cylindrical part of a bolt, as distinguished from the head.
  15. A general term for structural rolled steel of any cross section other than a plate.
  16. To cut by shearing. The machine used for shearing steel plates or angles. Also, in material an expression for the algebraic sum of all the external forces acting on one side of a section plane through the material.
  17. A graphical depiction of the magnitude of vertical shear force at any point along a beam or girder.
    Shear diagram
  18. An occurence when less than the total cross-sectional area of a member is connected, resulting in a decrease in efficiency of the section in the region of the connection.
    Shear lag
  19. Plates, welded studs, bolts and other steel shapes that are embedded in the concrete and located transverse to the direction of the shear force. They transmit shear loads introduced into the concrete by local bearing at the shear lug-concrete interface.
    Shear lugs
  20. A wall that in its own plane resists shear forces resulting from applied wind, earthquake or other transverse loads or provides frame stability.
    Shear wall
  21. A plate that is passed between horizontal rolls at the mill and then trimmed (sheared or gas cut) to the desired size on all edges, as distinguished from a Universal Mill Plate.
    Sheared plate
  22. A stress caused by vertical loads applied to a beam or girder and tending to slide one section along an adjacent section.
    Shearing stress
  23. A thin piece of structural steel used in filling the spaces allowed for erection clearance. They may be either strip shims or finger shims.
  24. A small, temporary weld made to hold component parts of a member together until they can be welded permanently.
    Shipping weld or Tack weld
  25. The area at a fabricating shop in which fabricated members are sorted and stored for shipment to the job site as required.
    Shipping yard
  26. The place where the component parts of a structure are fabricated into members.
  27. A summary of material required for fabricating the members shown on a particular drawing.
    Shop bill
  28. A bolt that is installed in the shop, as distinguished from a field bolt.
    Shop bolt
  29. A working drawing prepared for use in the shop.
    Shop drawing
  30. The coat of paint applied, if required, at the fabricating shop.
    Shop paint
  31. The lateral movement of a structure under the action of lateral loads, unsymmetrical vertical loads or unsymmetrical properties of the structure.
  32. An unrestrained beam that is supported at both ends only.
    Simple beam
  33. A loaded beam or girder in which the ends are free to rotate at the points of support.
    Simply supported
  34. To punch one hole at a time.
    Single punch
  35. The tendency to shear, or the resistance to shear, a single element or group of elements on one plane.
    Single shear
  36. The term used to describe a building frame. The frame may be of steel, concrete, wood or any combination of these materials.
  37. An illustration of a structural steel member, connection or detail made free-hand. Also, the individual illustrations of members and details presented on a shop drawing.
  38. A beam or girder is described as skewed when its flanges are parallel to the flanges of the supporting beam/girder, but the webs are inclined to each other.
  39. Parallel supports of timber or steel used to elevate members a convenient distance above the floor of a shop to make them more accessible.
  40. A term used to describe the exterior wall (covering) of a building. The skin may be brick, concrete, glass, metal panels, stone or a combination of any of these materials,
  41. A thick steel plate used as a column base or similarly. Also, a reinforced-concrete floor.
  42. A long tubular nut having a right-handed thread in one half and a left-handed thread in the other, used for joining two threaded rods and pulling them together to tighten them.
    Sleeve nut
  43. The ratio of the effective length of a column to the radius of gyration of the column, both with respect to the same axis of bending.
    Slenderness ratio
  44. A joint that transmits shear loads or shear loads in combination with tensile loads in which the bolts have been installed in accordance with Section 8.2 of the RCSC Specification for Structural Joints Using ASTM A325 or A490 Bolts, to provide a pretension in the installed bolt (clamping force on the faying surfaces), and with faying surfaces that have been prepared to provide a calculable resistance against slip.
    Slip-critical joint
  45. The bevel or inclination of one line with reference to another. It is measured by the tangent of the angle of inclination expressed in inches and fractions to a base of one foot.
  46. A beam or girder is described as sloped if its web is perpendicular to the web of the supporting member, but its flanges are not perpendicular to this face.
  47. A weld made in and filling a slot in one of the parts connected.
    Slot weld
  48. An elongated hole with semicircular ends and parallel sides. May be either short slots or long slots as defined by the AISC Manual of Steel Constrution.
    Slotted hole
  49. A joint in which the bolts have been installed in accordance with Section 8.1 of the RCSC Specification for Structural Joints Using ASTM A325 or A490 Bolts. The snug-tightened condition is the tightness that is attained with a few impacts of an impact wrench or the full effort of an ironworker using an ordinary spud wrench to bring the plies into firm contact.
    Snug tightened joint
  50. The distance between the supports of a beam, girder, truss, etc.
