2025|2026 Q&A | Instant Download Pdf
1. What is the primary purpose of a structural steel contractor?
To fabricate, erect, and install structural steel components for
buildings and other structures.
Rationale: The structural steel contractor is responsible for the
fabrication, erection, and installation of steel framing systems,
ensuring structural integrity.
2. What is the minimum allowable thickness for a steel plate used in
structural applications?
Varies based on design specifications and applicable codes.
Rationale: Minimum thickness depends on structural design
requirements, load conditions, and the applicable building code (e.g.,
AISC, Florida Building Code).
,3. When welding structural steel, what is the recommended electrode
type for carbon steel?
E7018 low-hydrogen electrode.
Rationale: E7018 is commonly used in structural steel welding for its
low-hydrogen properties, which minimize cracking.
4. Which standard governs the design of structural steel in Florida?
AISC Steel Construction Manual.
Rationale: The AISC Manual provides the authoritative guidelines for
design and construction of structural steel members in accordance
with Florida code requirements.
5. What is the purpose of a base plate in steel construction?
To distribute column loads to the foundation.
Rationale: Base plates provide a stable interface between steel
columns and foundations, preventing excessive stress and
settlement.
6. Which inspection method is used to detect surface cracks in welded
steel?
Visual inspection and dye penetrant testing.
Rationale: Visual inspection identifies obvious defects, while dye
penetrant testing can reveal surface cracks not visible to the naked
eye.
7. How often should scaffolding be inspected during steel erection?
Daily and after any incident that may affect stability.
, Rationale: Regular inspection ensures the safety and stability of
scaffolding used in steel erection.
8. What is the minimum steel grade commonly used for structural
shapes?
ASTM A36.
Rationale: ASTM A36 is a widely used carbon steel with sufficient
strength and ductility for structural shapes.
9. Which type of connection allows for some rotation in steel framing?
Bolted slip-critical connection.
Rationale: Slip-critical connections resist movement through friction
but allow minor rotational adjustments during erection.
10. What is the main purpose of bracing in steel structures?
To provide lateral stability.
Rationale: Bracing resists wind, seismic, and other lateral forces to
prevent buckling or sway.
11. How should steel members be stored on-site to prevent
damage?
On level, dry surfaces with proper supports.
Rationale: Proper storage prevents warping, corrosion, and damage
before installation.
12. What safety equipment is mandatory for workers at heights
above 6 feet?
, Fall protection, including harnesses and lanyards.
Rationale: OSHA requires fall protection for employees working at
elevated heights to prevent serious injuries.
13. How is the allowable stress of steel determined?
Based on yield strength and applicable design codes.
Rationale: Allowable stress is a fraction of yield strength, ensuring a
factor of safety according to AISC or other relevant codes.
14. What is the purpose of a girder in steel construction?
To support and distribute loads from beams to columns.
Rationale: Girders act as primary load-carrying members,
transferring weight to the structural framework.
15. What is the difference between shop drawings and as-built
drawings?
Shop drawings detail fabrication; as-built drawings reflect final
construction.
Rationale: Shop drawings guide fabrication, while as-built drawings
document the completed structure.
16. What is the primary cause of brittle fracture in steel?
Low temperature or high stress conditions.
Rationale: Brittle fracture occurs when steel loses ductility, often at
low temperatures or high stress concentrations.
