What are the two types of wire joint reinforcement mentioned in masonry construction?

In masonry construction, wire joint reinforcement is utilized to enhance the strength and stability of masonry walls. The two types recognized in the field are ladder-type and truss-type reinforcements.

Ladder-type reinforcement consists of two horizontal wires connected by vertical wires, creating a 'ladder' appearance. This design is effective in providing lateral support and helps resist cracking in masonry walls, making it suitable for both brick and block masonry applications.

Truss-type reinforcement features a more triangular configuration, which distributes loads more evenly across the masonry structure. This type can provide superior resistance against lateral forces, adding strength and rigidity to the wall.

Both types serve critical roles in increasing the structural integrity of masonry work, allowing for better performance in various environmental conditions. The options that refer to diagonal, cross, square, or round types do not accurately describe the standard forms of joint reinforcement commonly recognized in masonry practice.
