Deformation Failure Theory For Stack-Bond Brick Masonry Prisms In Compression

Compressive tests of stack-bond masonry prisms are used in the United States to evaluate the quality of masonry as a basis for design allowable stresses and as a research experiment. Hence, an understanding of unit-mortar interaction upon prism strength and deformation is important. The multi-axial constituent properties of brick and mortar were determined under carefully controlled conditions for four types of mortar and two types of brick. Using this data a deformation failure theory was developed for stack-bond, solid unit prisms under compressive loading.
