What role do steel ties play in brick wall construction?

Steel ties play a crucial role in the structural reinforcement of brick walls. Their primary function is to connect the brick masonry unit to a backup structure, often made of concrete or steel, ensuring that both materials work together to withstand various loads and forces, such as wind, seismic activity, and the weight of the wall itself. This connection significantly enhances the overall stability and durability of the wall.

In addition to providing reinforcement, steel ties help to distribute loads evenly across the wall, reducing the risk of cracking and deformation. Their usage is essential in maintaining the integrity of taller walls or walls subjected to lateral forces. This integration of steel ties is a standard practice in masonry construction, ensuring compliance with building codes and safety standards.

While the other options touch upon aspects related to construction, they do not accurately describe the specific purpose and importance of steel ties in brick wall construction.
