Which walls provide structural support and contribute to the building’s structural integrity?

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

Answer: (A)

The main concept here is that walls that carry and transfer loads are the ones that provide structural support. Load-bearing walls form the vertical load path for the building, taking weight from floors, ceilings, and the roof and directing it down to the foundation. Because they physically support the structure, they play a direct role in the building’s stability; removing or weakening one without compensating support can compromise safety.

Non load-bearing walls, by contrast, do not carry vertical loads. They simply divide spaces or enclose rooms. Interior partition walls fall into this category, and exterior decorative walls are intended for appearance rather than structural support, though exterior walls in traditional construction can carry loads if they are designed as part of the structure.
