SUMMARY
Section properties of brick masonry materials and assemblages are required whenever a rational design of brick masonry structural elements is developed following the criteria of the MSJC Code and Specifications. This Technical Notes provides a summary of section properties of brick masonry. Section properties of clay and shale masonry units, steel reinforcement and typical brick masonry assemblages are given.
The information and suggestions contained in this Technical Notes are based on the available data and the experience of the engineering staff of the Brick Institute of America. The information contained herein must be used in conjunction with good technical judgment and a basic understanding of the properties of brick masonry. Final decisions on the use of the information contained in this Technical Notes are not within the purview of the Brick Institute of America and must rest with the project architect, engineer and owner.
