Which term describes the steel component used in constructing buildings for added strength and stability?

• A. Structural Steel
• B. Fire Protection
• C. Building Code
• D. Conflagration

Answer: (A)

This question tests knowledge of terminology for the steel framework that gives a building its strength and stability. Structural steel refers to the engineered steel components—beams, columns, and frames—that form the skeleton of a structure. These elements provide the primary support, resist loads from gravity and lateral forces, and allow the building to behave predictably under stress. Steel’s high strength‑to‑weight ratio and ductility make it ideal for spanning large distances and withstanding movements without sudden failure. In practice, these steel members are connected into a rigid frame that supports floors and walls and maintains overall stability. The other terms refer to different concepts: fire protection is about materials or systems that resist fire, a building code is a set of regulations, and conflagration means a large destructive fire. So the steel component used for added strength and stability is structural steel.
