Briefly, structural masonry is a construction system in which the walls of the building perform a structural function, using masonry units arranged in a way that is self-supporting and load-bearing. The walls will evenly distribute the load to the foundation and later into the ground.
Stacked in layers, the bricks, blocks, or stones may or may not be connected by a binder (mortar) and steel reinforcements that heavily influence the mechanical properties of the wall, dimensioned to resist active forces.
