What distance must the individual masonry corbels be designed relative to the individual masonry unit height?

The requirement that individual masonry corbels must be designed to extend not more than half the height of the individual masonry unit is based on structural stability and integrity. When corbels extend beyond this specified limit, they can compromise the load-bearing capabilities of the wall. Extending corbels too far can lead to potential failure under load, as the cantilever effect increases with the distance, creating additional stress on the wall and reducing its overall stability.

Designing corbels to this specific dimension ensures that they provide necessary support while maintaining sufficient strength and safety for the structure. This practice adheres to industry standards and codes, promoting long-term durability and resistance to structural issues that might arise from improper corbel design.
