1. What is the primary material used in structural steel construction?
a) Aluminum
b) Wood
c) Steel
d) Copper
Steel is the base material for structural steel construction due to its
strength and durability.
2. Which type of steel is commonly used in structural steel framing?
a) Stainless steel
b) Tool steel
c) Carbon structural steel
d) Alloy steel
, Carbon structural steel is most commonly used because of its balance
of strength and cost-effectiveness.
3. What does ASTM stand for?
a) American Steel Testing Method
b) American Society for Testing and Materials
c) Association of Structural Testing Methods
d) American Standards for Technical Materials
ASTM sets the standards for materials, including structural steel.
4. In steel design, what does the abbreviation “Fy” stand for?
a) Young’s Modulus
b) Yield Strength
c) Flexural Rigidity
d) Shear Modulus
Fy represents yield strength, the stress at which steel begins to
deform plastically.
5. Which welding process is most commonly used in structural steel
fabrication?
a) TIG welding
b) Oxy-fuel welding
c) Shielded Metal Arc Welding (SMAW)
d) Brazing
SMAW is widely used for structural steel due to versatility and
strength of welds.
, 6. What is the minimum shop temperature for structural steel welding as
per AWS standards?
a) 0°F
b) 100°F
c) 50°F
d) 200°F
50°F is the minimum temperature to prevent weld cracking during
fabrication.
7. Which type of load is caused by wind pressure on a steel structure?
a) Dead load
b) Lateral load
c) Live load
d) Impact load
Wind pressure applies lateral loads, acting horizontally on structures.
8. In bolted connections, what does "slip-critical" refer to?
a) Loose bolts allowed
b) Friction between surfaces resists load
c) Bolts carry shear directly
d) Bolts only carry tension
Slip-critical connections depend on friction between contact surfaces,
not bolt shear.
9. What is the primary purpose of primer paint on structural steel?
a) Strength increase
