Masonry
Masonry construction involves constructing structures from separate components that are typically combined using mortar. When designing masonry constructions, my go-to material is concrete blocks, with the option for vertical steel reinforcing when needed. Masonry is an excellent material for building load-bearing walls because of its strength in withstanding compression loads and pressures. Other materials used in masonry are glass blocks, stone, and brick. Although masonry is a solid and fireproof material, the quality of the mortar and the craftsmanship might affect it.
In my firm, there has been a rise in the design of multi-story structures using masonry for load-bearing walls. Depending on the number of stories and the weight of the walls, the structural system usually consists of concrete floors supported by a combination of masonry and reinforced concrete walls. Masonry walls with windows or other openings require lintels or horizontal beams to support the weight of the wall above the opening. Although masonry accommodates huge wall openings less than concrete or steel framing, it can still be cost-effective if the wall segments’ lengths are not excessively short and the frame and aperture sizes are suitable.
Buildings with multiple stories can be constructed by piling load-bearing masonry walls on top of one another. The weight of all the above levels is accumulated to form the load on the first-floor masonry wall. As a result, the walls on the lower floors need to be stronger than those on the upper floors. This can be accomplished using concrete grout and steel bars to reinforce the spaces between the bottom masonry walls. More muscular masonry walls have more steel bars and closer grouted core spacing. Large concrete or steel transfer beams are needed to support the wall above specified openings like parkade drive aisles, which prevent a load-bearing masonry wall from extending down to the base.
