Which type of masonry neglects the effects of stresses in reinforcement?

The type of masonry that neglects the effects of stresses in reinforcement is plain masonry. This form of masonry consists strictly of stone or brick units that are laid without any significant use of reinforcing materials. As a result, plain masonry does not account for the incorporation of steel reinforcement bars or other types of reinforcements that help to manage tensile stresses within the structure. Consequently, plain masonry relies solely on the compressive strength of the masonry units, making it more vulnerable to cracking and failure under lateral or tensile loads.

In contrast, solid masonry, while it can indicate a sturdy construction method, often includes some degree of support or reinforcement, thus addressing stress factors to some extent. Unreinforced masonry also implies the absence of reinforcement, similar to plain masonry; however, the context generally emphasizes the ability of the structure to withstand typical stresses without additional support, which might not be the same way as plain masonry is characterized. Glass masonry refers to elements that incorporate glass units and often rely on modern materials and methods, which again diverges from the characteristics of plain masonry. Hence, plain masonry is the most fitting answer in this context.
