Which term refers to steel used in the construction of buildings for added strength and stability?

• A. Reinforced Concrete
• B. Structural Steel
• C. Architecture
• D. Fire Protection

Answer: (B)

This question tests understanding of the term for steel pieces that form a building’s structural framework. Structural steel refers to the steel members—beams, columns, and other shapes—that are specifically designed to carry loads and resist bending, shear, and torsion in the building’s frame. Its high strength-to-weight ratio and ductility allow for stable, efficient construction, enabling taller and more resilient structures.

Reinforced concrete, while it also uses steel, describes concrete elements that are strengthened with embedded steel reinforcing bars, not the structural steel components used to form the frame. Architecture is the design discipline focused on the appearance, function, and organization of spaces, not the material used for structural members. Fire protection covers safety measures to limit fire impact, not the material’s structural role.

So the term that best fits “steel used in the construction of buildings for added strength and stability” is structural steel.
