Which statement best describes a bond beam again for testing purposes?

• A. A continuous tie across walls to resist lateral loads and connect structure; used in masonry or framed walls.
• B. A decorative trim at the top of a wall.
• C. An insulation layer beneath slabs.
• D. A leveling device for slab surfaces.

Answer: (A)

A bond beam is a continuous structural member that runs across the tops of walls to tie them together and resist lateral forces like wind or seismic loads. It creates a single, stable load path that helps walls transfer forces to columns or other parts of the frame, preventing walls from spreading or buckling at the top. In practice, it’s usually a reinforced concrete (or grout-filled masonry) beam placed across the top of masonry walls, often spanning openings and reinforced with steel bars to provide continuous strength. It’s used in both masonry and framed wall systems to maintain rigidity and connection, not decorative trim, insulation, or a leveling device for slabs.
