DOES THE WIDTH OF THE REINFORCEMENT BENEFICIALLY AFFECT THE STRUCTURAL PERFORMANCE?

Reinforcement used in crack control does not require a specific width, since the only thing that counts in this case is the area of steel section.

By contrast, the width of the reinforcement has a role to play when it has a structural function, and that by increasing the mechanical arm, you increase at the same proportion the horizontal bending strength of the walls in the masonry.
