1. Name one reason why steel construction
   requires advanced planning.

• Lead times associated with fabrication
• Field material management (laydown and
  staging areas, tracking)
• Crane placement and capacity
2. Identify the meaning of the following notations concerning a
   piece of steel defined as an A36, W16X64 beam.


  •   Yield strength, Fy = _____
  •   W = ________
  •   16 = ________
  •   64 = ________
2. Identify the meaning of the following notations concerning a
   piece of steel defined as an A36, W16X64 beam.


  • Yield strength, Fy = 36 ksi
  • W = W shape
  • 16 = depth of member from outside flange to
    outside flange is 16”
  • 64 = weight per linear foot is 64 lbs/l.f.
3. What does a shielded metal arc welding process protect
   against?
3. What does a shielded metal arc welding process protect
   against?


  • Protects the weld from exposure to oxygen
    and nitrogen
  • Why?
     – Those atmospheric gases produce a brittle weld
4. Which steel connection is described by:



  • Securing the flanges at the connection:
     – __________________
  • Securing only the web at the connection:
     – __________________
4. Which steel connection is described by:



  • Securing the flanges at the connection:
     – Moment connection
  • Securing only the web at the connection:
     – Shear connection
5. Fill in the blank.


  • _______– Planned load the structure must
    carry under normal conditions that would be
    moved across the structure’s surface. E.g.
    Humans, furniture, equipment, or uninstalled
    materials
  • _______– Stationary, permanent loads; that is,
    the weight of all the installed materials. E.g.
    concrete.
5. Fill in the blank.


  • Live Load – Planned load the structure must
    carry under normal conditions that would be
    moved across the structure’s surface. E.g.
    Humans, furniture, equipment, or uninstalled
    materials
  • Dead Load – Stationary, permanent loads;
    that is, the weight of all the installed materials.
    E.g. concrete.
