Which walls do not contribute to the building's structural integrity?

• A. Curtain walls
• B. Load-bearing walls
• C. Non load-bearing walls
• D. Exterior walls

Answer: (C)

In construction, the walls that actually carry the building’s loads are the ones contributing to structural integrity. Non-load-bearing walls exist only to partition space and finish surfaces—they don’t support floors or roofs and can be removed or relocated without affecting stability. Curtain walls are exterior façades that attach to the structural frame and don’t carry loads, while exterior walls in some designs can be structural, though they may also be non-structural in others. The term that identifies walls not contributing to the structure is non-load-bearing walls, making them the correct choice.
