What is the minimum specification for horizontal joint reinforcing?

• A. One deformed longitudinal #6 wire
• B. Two deformed longitudinal #9 wires
• C. Three cold-drawn steel wires
• D. One continuous piece of flat steel

Answer: (B)

The choice of two deformed longitudinal #9 wires as the minimum specification for horizontal joint reinforcing is grounded in the requirements for ensuring structural integrity and stability within masonry construction. Horizontal joint reinforcement plays a crucial role in the distribution of loads and improves the partitioning of forces throughout the masonry wall. Using two deformed longitudinal wires instead of a single wire provides redundancy and allows for enhanced tensile strength along the length of the joint. Deformed wires are specifically designed with surface indentations that create better bonding with the surrounding mortar, which is essential for effective load transfer. The #9 gage is sufficiently robust to handle the stresses that may be encountered in various masonry applications while remaining manageable in terms of installation and material weight. This specification aligns with industry standards that prioritize safety and reliability in construction practices, making it an essential guideline for construction professionals to follow while working with masonry materials.
