Answer:
The most common type of large-scale reinforced brick masonry wall is characterized by its use of reinforcing steel and grout between the courses of brick. This type of wall is known as a reinforced brick masonry wall (RB wall).
In an RB wall, a reinforcing steel mesh or reinforcing bars are placed in the mortar joints between brick courses to provide additional support and strength. Grout is then poured into the voids between the reinforcing steel and the brick masonry to further strengthen the wall.
The use of reinforcing steel and grout in RB walls helps to increase their resistance to lateral forces, such as wind loads or seismic events. They are commonly used in the construction of buildings, bridges, and other structures.
