1. What is the primary purpose of a base plate in steel construction?
A) To anchor the steel to concrete
B) To allow for expansion of steel
C) To provide aesthetic finish
D) To support electrical conduits
A) To anchor the steel to concrete
Rationale: The base plate distributes the load of the steel column onto
the concrete foundation and provides anchorage.
2. Which welding process is most commonly used for structural steel
in NYC construction?
A) Oxy-acetylene welding
B) Shielded Metal Arc Welding (SMAW)
C) Gas Tungsten Arc Welding (GTAW)
D) Electron Beam Welding
B) Shielded Metal Arc Welding (SMAW)
Rationale: SMAW is widely used in field welding for structural steel
due to portability and suitability for outdoor conditions.
, 3. What is the standard minimum yield strength for A992 structural
steel in building construction?
A) 36 ksi
B) 50 ksi
C) 42 ksi
D) 60 ksi
B) 50 ksi
Rationale: A992 steel, commonly used for structural shapes, has a
minimum yield strength of 50 ksi according to ASTM standards.
4. When rigging steel beams, the working load limit (WLL) should be
based on:
A) 50% of the sling’s rated capacity
B) The sling’s rated capacity
C) Twice the sling’s rated capacity
D) The weight of the beam minus 10%
B) The sling’s rated capacity
Rationale: WLL must never exceed the rated capacity of the rigging
equipment to ensure safe lifting.
5. Which tool is used to align bolt holes in steel connections?
A) Hammer drill
B) Drift pin
C) C-clamp
D) Torque wrench
B) Drift pin
Rationale: Drift pins are used to align bolt holes in steel members
before bolts are installed.
6. The primary hazard of working at heights in ironworking is:
A) Noise exposure
, B) Fall from elevation
C) Electrical shock
D) Repetitive motion injury
B) Fall from elevation
Rationale: Falls are the leading cause of injuries and fatalities among
ironworkers, making fall protection critical.
7. What is the correct torque for an A325 bolt in a snug-tight
connection?
A) 50% of ultimate tensile strength
B) As specified by manufacturer
C) Tight enough to remove all slack
D) Twice the snug-tight torque
C) Tight enough to remove all slack
Rationale: Snug-tight means the bolt is tightened until members are in
firm contact without over-torquing.
8. Which OSHA standard governs steel erection safety in NYC?
A) 1910 Subpart D
B) 1926 Subpart R
C) 1926 Subpart M
D) 1910 Subpart K
B) 1926 Subpart R
Rationale: OSHA 1926 Subpart R specifically addresses steel erection,
including fall protection, rigging, and hoisting.
9. What is the purpose of a stiffener plate in a steel beam?
A) Increase beam length
B) Reduce local buckling
C) Serve as decorative element
D) Anchor the beam to foundation
, B) Reduce local buckling
Rationale: Stiffener plates strengthen areas of a beam under
concentrated loads or near connections to prevent buckling.
10. Which type of scaffold is most suitable for ironworkers
erecting steel beams at height?
A) Suspended scaffold
B) Pump jack scaffold
C) Tube and clamp scaffold
D) Ladder scaffold
C) Tube and clamp scaffold
Rationale: Tube and clamp scaffolds are flexible and can adapt to
irregular steel structures during erection.
11. Which type of connection is considered slip-critical?
A) Welded connection
B) Bearing-type bolted connection
C) Friction-fit bolted connection
D) Riveted connection
C) Friction-fit bolted connection
Rationale: Slip-critical connections rely on friction between faying
surfaces to resist movement, unlike bearing-type connections.
12. When cutting steel with an oxy-acetylene torch, what is the
main safety concern?
A) Carbon monoxide poisoning
B) Falling objects
C) Eye injury from sparks
D) Electrical shock
