Building Code Requirements for Masonry Structures and Specifications for Masonry Structures reflects the latest industry consensus for design and construction of masonry structures. This new Standard has been substantially revised, and many new requirements have been added. Some of the major updates include: Strength design procedures for autoclaved aerated concrete (AAC) masonry; Complete revision in prestressed masonry design philosophy to a strength design basis with service load checks; Revised maximum reinforcement limits for strength design; harmonized splice length requirements for allowable-stress design and strength design; and clarification on limits for empirical design in high wind areas.
