1. In structural steel erection, what is the primary purpose of a
turnbuckle in a temporary bracing system?
A. To increase dead load on columns
B. To provide electrical grounding between members
C. To adjust and tension bracing members for alignment and stability
D. To permanently weld structural joints during erection
Answer: C
A turnbuckle is used to finely adjust the length and tension of bracing
cables or rods, allowing ironworkers to plumb, level, and stabilize
structural members during erection.
2. Which type of steel connection is most commonly used for rapid field
assembly in high-rise steel construction?
A. Riveted connection
B. Welded moment connection only
C. High-strength bolted connection
D. Adhesive bonded connection
Answer: C
High-strength bolted connections are widely used because they allow
, faster assembly, easier alignment, and reliable structural
performance in field conditions.
3. What is the safest method for guiding a suspended steel beam into
position?
A. Using bare hands while the load is swinging
B. Using tag lines attached to both ends of the beam
C. Standing directly beneath the load for better control
D. Pushing the beam using a ladder
Answer: B
Tag lines allow workers to control and stabilize suspended loads from
a safe distance, reducing the risk of being struck by swinging steel
members.
4. Which device is primarily used to lift steel members vertically during
erection?
A. Come-along
B. Chain fall
C. Crane
D. Hydraulic jack
Answer: C
Cranes are the primary lifting equipment used in structural steel
erection to safely raise and position heavy members at height.
5. What is the main purpose of a spud wrench in structural ironwork?
A. Cutting rebar
B. Tightening bolts and aligning holes in steel members
C. Measuring wind speed at elevation
D. Welding steel joints
Answer: B
A spud wrench is used to align bolt holes and tighten bolts during
steel assembly, making it essential for fit-up operations.
,6. What is the most critical factor when selecting a crane for steel
erection?
A. Color of the crane
B. Maximum lifting capacity at required radius
C. Number of operators available
D. Fuel tank size
Answer: B
Crane selection is primarily based on its lifting capacity at a specific
working radius to ensure safe handling of loads.
7. What is the purpose of drift pins during steel erection?
A. To permanently fasten structural steel
B. To enlarge holes for bolts
C. To align holes in steel members before bolting
D. To measure structural deflection
Answer: C
Drift pins are tapered tools used to align bolt holes in steel members
to facilitate proper bolting during assembly.
8. Which hazard is most associated with working at height during steel
erection?
A. Radiation exposure
B. Falls from elevation
C. Chemical burns
D. Noise-induced hearing loss only
Answer: B
Falls from elevation are the leading hazard in steel erection work,
requiring strict fall protection systems and procedures.
9. What is the function of a safety net in structural steel work?
A. To store tools at elevation
B. To catch falling workers or debris
, C. To support steel beams permanently
D. To measure wind load
Answer: B
Safety nets are installed below work areas to arrest falls of workers
or materials, reducing injury risk.
10. Which term describes the temporary support used to hold
structural steel in place before permanent connections are completed?
A. Foundation pad
B. Shoring or temporary bracing
C. Anchor bolt assembly
D. Grout pad
Answer: B
Temporary bracing or shoring stabilizes structural members until
permanent connections are fully secured.
11. What is the primary purpose of torque in bolted steel
connections?
A. To weaken the bolt for removal
B. To ensure correct clamping force between connected members
C. To lubricate the bolt threads
D. To prevent rust only
Answer: B
Proper torque ensures the correct clamping force, which is essential
for structural integrity of bolted joints.
12. Which tool is used to verify vertical alignment of structural
columns?
A. Spirit level or plumb bob
B. Micrometer
C. Caliper
D. Tachometer
