What is the minimum overlap length required for wire joint reinforcement lengths?

The minimum overlap length required for wire joint reinforcement is 6 inches. This overlap is critical because it ensures the structural integrity and load distribution across joints in masonry construction. When two pieces of wire reinforcement are joined, the overlap allows for the effective transfer of tension and shear forces between the segments, helping to maintain the strength of the wall or structure.

A shorter overlap may not provide sufficient mechanical interlock, potentially weakening the joint and compromising the overall stability of the masonry. This standard is established in masonry construction codes and guidelines, underscoring the importance of proper reinforcement practices in ensuring the durability and safety of the structure.
