1. Which property of structural steel primarily allows it to undergo
significant deformation before failure?
a. Brittleness
b. Elasticity
c. Ductility
d. Hardness
Rationale: Ductility is the ability of a material to deform plastically
under load before fracturing. Structural steel is valued for its ductility
because it can absorb and redistribute stresses and provide warning
through deformation before catastrophic failure.
2. What is the primary purpose of a structural steel erection plan?
,a. To determine paint colors
b. To establish payroll requirements
c. To define the sequence, methods, equipment, and safety
requirements for erection
d. To calculate employee vacation time
Rationale: An erection plan establishes how structural members will
be delivered, lifted, positioned, temporarily braced, connected, and
made stable. Proper planning reduces erection hazards and helps
ensure the structure is assembled according to the design.
3. Which connection is commonly used to transfer shear and tension
between steel members?
a. Paint connection
b. Bolted connection
c. Insulation connection
d. Expansion-joint seal
Rationale: Structural bolted connections can transfer shear, tension,
or combinations of both when properly designed and installed. The
bolt type, diameter, number, hole configuration, and installation
method must meet the applicable structural requirements.
4. What is the main function of a structural column?
,a. Provide waterproofing
b. Transfer vertical and other structural loads to the foundation
c. Prevent corrosion
d. Provide architectural finishes only
Rationale: Columns are primary load-bearing members that transfer
loads from beams, floors, roofs, and other components toward the
foundation. They must be properly aligned, connected, braced, and
supported.
5. Which steel shape is commonly identified by its wide flanges and
used as a beam or column?
a. Round bar
b. Angle
c. Wide-flange section
d. Flat washer
Rationale: Wide-flange sections have relatively broad flanges
connected by a web and are extensively used for structural beams and
columns. Their geometry provides efficient resistance to bending and
axial loads.
6. What is the purpose of temporary bracing during steel erection?
, a. To replace permanent foundations
b. To improve paint adhesion
c. To maintain stability until the permanent structural system is
complete
d. To reduce the weight of steel members
Rationale: Partially erected steel structures may not yet have their
final load paths or lateral stability. Temporary bracing, guying, or
other stabilization methods prevent movement or collapse until
permanent connections and bracing are installed.
7. What does a steel erection crane primarily provide?
a. Welding gas
b. Concrete reinforcement
c. Lifting and positioning capacity for structural members
d. Surface preparation
Rationale: Cranes are used to hoist structural steel from staging areas
and position members at their required elevations. Lift planning must
account for load weight, radius, rigging, wind, crane capacity, and site
conditions.
8. Before lifting a structural steel member, what should be verified
first?
