Compressive Strength of Masonry

Structural performance of masonry is based on the physical characteristics of its components and on the construction methods used in assembling these components. The strength of masonry is influenced by the structural properties of units, grout, mortar and reinforcement. In engineered masonry structures, the required strength of structural elements is determined by distributing design loads to the various resisting elements in accordance with a structural analysis. After the required strength is determined, the designer uses it as a basis for specifying f´m, which is defined as the "specified compressive strength of masonry". This property is noted in the project documents and is used in accordance with masonry design codes to establish allowable stresses for masonry elements.
