Which type of bond pattern is essential for the stability of a masonry wall?

• A. Random bond
• B. Reinforced bond
• C. Running bond
• D. Stacked bond

Answer: (C)

The running bond pattern is essential for the stability of a masonry wall due to its configuration, which alternates the vertical joints of the masonry units. This means each course of bricks overlaps the ones below it, creating a continuous, interlocking pattern. This overlapping helps distribute loads more evenly across the wall, minimizing the risk of structural failure. Furthermore, the running bond pattern provides good lateral stability, allowing the wall to resist lateral forces such as wind. The staggered joints formed by this pattern also enhance the overall strength of the wall by preventing long vertical seams, which can become weak points. In contrast, other bond patterns, such as stacked bond, do not provide this interlocking and can lead to greater instability, as they may have continuous vertical joints that do not distribute forces effectively. Random bond, while visually interesting, may also lack the consistent performance characteristics necessary for structural integrity. Reinforced bond typically involves the incorporation of steel reinforcement but is not a standard bond pattern itself and is instead applied as a supplement to enhance strength in specific scenarios.
