Structural design of AAC masonry
AAC MASONRY IS DESIGNED according to the provisions of Appendix A of the MSJC Code (MSJC 2008), referenced by model codes throughout the United States. Design of AAC masonry is similar to strength design of clay or concrete masonry and is based on a specified compressive strength. Compliance with that specified compressive strength is verified by compressive strength testing of AAC cubes, using ASTM C1386, when the masonry-type elements of AAC are fabricated. Extensive practical guidance on design with AAC masonry is provided in the 5th edition of the Masonry Designers Guide (MDG 2007).
Combinations of flexure and axial load
AAC MASONRY IS DESIGNED for combinations of flexure and axial load using the same principles as for the strength design of clay or concrete masonry. Nominal capacity is computed assuming plane sections, tension steel at yield, and an equivalent rectangular compression block.
Bond and development of reinforcement
REINFORCEMENT in AAC masonry consists of deformed reinforcement placed in grouted vertical cores or bond beams and surrounded by masonry grout. Development and splice requirements for deformed reinforcement in grout are identical to those used for clay or concrete masonry. Conservatively, the AAC material is not considered when calculating cover for splitting resistance.

Shear and bearing
AS WITH CLAY or concrete masonry, the shear resistance of AAC masonry is computed as the summation of a shear resistance due to the AAC itself, and a shear resis-
