What function does a bond beam serve in a masonry structure?

1. It acts as insulation

2. It increases aesthetic appeal

3. It provides stability at the top of a wall

4. It's used exclusively for decoration

The correct answer is: It provides stability at the top of a wall

A bond beam serves a crucial structural function in masonry construction. Specifically, it provides stability at the top of a wall. This horizontal reinforcement helps distribute loads, ensuring that the wall remains stable and can support any superimposed loads, such as roof structures or upper floors. By acting as a horizontal tie, the bond beam helps to prevent movement and maintain the integrity of the structure against forces such as wind or seismic activity. While insulation, aesthetic appeal, and decorative purposes can be important considerations in masonry work, those roles do not pertain to the primary function of a bond beam. Its main purpose is to enhance structural stability, making it essential for the overall safety and durability of the masonry wall.
