Question 1
What is the primary purpose of structural steel in building construction?
A. Electrical grounding
B. Thermal insulation
C. Load-bearing support
D. Fireproof coating
Answer: C. Load-bearing support
Rationale: Structural steel is primarily used to resist and transfer loads safely
through a building’s framework to the foundation. It provides strength, stability,
and rigidity, making it ideal for supporting dead loads, live loads, wind, and
seismic forces.
Question 2
Which standard governs steel welding qualifications in structural steel fabrication?
A. AWS D1.1
B. ASTM A36
C. AISC 360
D. OSHA 1926
Answer: A. AWS D1.1
Rationale: AWS D1.1 is the Structural Welding Code – Steel, which establishes
,requirements for welding procedure qualifications, welder certification, and
inspection standards for structural steel applications.
Question 3
What is the most common shape used for steel beams in building frames?
A. Angle iron
B. I-beam
C. Flat bar
D. Pipe section
Answer: B. I-beam
Rationale: I-beams are widely used because their geometry provides high
resistance to bending while minimizing material use, making them efficient for
spanning loads in structural systems.
Question 4
What does ASTM A36 primarily specify?
A. Aluminum grades
B. Structural steel carbon content and properties
C. Welding electrode types
D. Bolt torque values
Answer: B. Structural steel carbon content and properties
Rationale: ASTM A36 defines the chemical composition, mechanical properties,
and strength requirements for structural carbon steel commonly used in
construction.
Question 5
Which force is most critical for lateral load design?
A. Compression
,B. Shear
C. Wind and seismic forces
D. Tension from dead load
Answer: C. Wind and seismic forces
Rationale: Lateral loads such as wind and earthquakes apply horizontal forces
that must be resisted by bracing systems and structural frames to maintain
stability.
Question 6
What is the function of gusset plates in steel structures?
A. Provide insulation
B. Connect structural members at joints
C. Reduce corrosion
D. Increase concrete strength
Answer: B. Connect structural members at joints
Rationale: Gusset plates are steel plates used to connect beams, columns, and
bracing members, distributing loads at structural joints effectively.
Question 7
Which bolt type is most commonly used in structural steel connections?
A. Carriage bolts
B. Lag bolts
C. High-strength structural bolts
D. Sheet metal screws
Answer: C. High-strength structural bolts
Rationale: High-strength bolts (such as ASTM A325 or A490) are designed for
load-bearing steel connections requiring controlled tension and shear resistance.
, Question 8
What is the primary purpose of a moment connection?
A. Allow rotation
B. Transfer bending forces between members
C. Reduce steel weight
D. Increase corrosion resistance
Answer: B. Transfer bending forces between members
Rationale: Moment connections are rigid joints that transfer bending moments,
shear, and axial forces, creating continuous frame behavior.
Question 9
Which material property defines resistance to deformation under load?
A. Density
B. Elastic modulus
C. Ductility
D. Hardness
Answer: B. Elastic modulus
Rationale: Elastic modulus measures a material’s stiffness and ability to resist
elastic deformation under applied stress.
Question 10
What is the minimum slope requirement for roof drainage in steel-framed
structures?
A. 1/8 inch per foot
B. 1/4 inch per foot
C. 1 inch per foot
D. No slope required
