1. Which ASTM standard governs structural steel shapes, plates, and bars
for building construction?
A. ASTM A36
B. ASTM A992
C. ASTM A6
D. ASTM A500
Rationale: ASTM A6 specifies general requirements for structural
steel shapes, plates, and bars, including tolerances and markings.
2. What is the primary purpose of a gusset plate in structural steel
construction?
A. To support roofing materials
B. To serve as a decorative element
C. To connect beams and columns or truss members
D. To prevent corrosion
Rationale: Gusset plates are used to join structural members,
typically in trusses or bracing systems, providing stability and load
transfer.
3. Which type of welding is most commonly used for field connections in
structural steel erection?
A. Spot welding
B. Shielded Metal Arc Welding (SMAW)
C. Gas Tungsten Arc Welding (GTAW)
D. Friction Stir Welding
, Rationale: SMAW is widely used in field applications due to its
portability, simplicity, and suitability for thick steel members.
4. What does “bolt slip-critical connection” refer to?
A. A bolted connection that allows some movement
B. A bolted connection where friction prevents movement under
load
C. A welded connection under tension
D. A temporary connection during erection
Rationale: Slip-critical bolts rely on friction between faying surfaces
to resist loads, as opposed to bearing-type bolts.
5. Which paint system is commonly specified for steel exposed to harsh
outdoor conditions?
A. Latex paint
B. Epoxy primer only
C. Zinc-rich primer with urethane topcoat
D. Acrylic paint
Rationale: Zinc-rich primers provide galvanic protection, and a
urethane topcoat ensures durability and weather resistance.
6. The standard for hot-rolled structural steel shapes is ASTM:
A. A36
B. A992
C. A500
D. A53
Rationale: ASTM A992 specifies chemical composition, mechanical
properties, and tolerances for hot-rolled shapes used in building
construction.
7. What is the minimum welding electrode size typically used for
structural steel field welds?
A. 1/16 inch
B. 1/8 inch
C. 3/16 inch
D. 1/4 inch
Rationale: 3/16 inch electrodes are commonly used for field welds on
structural members to ensure proper penetration and strength.
, 8. In structural steel design, the term “L/360” refers to:
A. Maximum beam depth
B. Maximum deflection allowed
C. Load factor
D. Steel grade
Rationale: L/360 indicates the maximum allowable deflection as a
fraction of the span length.
9. Which type of steel member is primarily used to resist bending
moments?
A. Column
B. Beam
C. Gusset plate
D. Base plate
Rationale: Beams are horizontal members designed to resist bending
moments due to loads applied perpendicular to their longitudinal
axis.
10. What is the purpose of a base plate in steel construction?
A. To act as a decorative feature
B. To prevent corrosion at the foundation
C. To distribute column loads to the foundation
D. To connect beams
Rationale: Base plates spread column loads evenly to the foundation
and provide a stable bearing surface.
11. When steel is exposed to fire, it loses strength significantly at
temperatures above:
A. 200°F
B. 400°F
C. 1000°F
D. 1500°F
Rationale: Structural steel retains most strength up to ~1000°F;
above this temperature, it softens and may fail.
12. Which type of connection is most suitable for transferring axial
tension?
A. Shear plate
B. Tension bolted connection
