This Standard was prepared by the Standards Australia Committee BD-004, Masonry Structures, to supersede AS 3700—2011.

The objective of this Standard is to provide minimum requirements for the design and construction of unreinforced, reinforced and prestressed masonry, including built-in components.

The principal changes from the 2011 edition of the Standard include the following:

(b) Inclusion of provisions for stack bonded masonry.

(c) Compressive strength of grouted masonry.

(d) Compression design of reinforced masonry.

(e) Concentrated loads in reinforced masonry.

(f) Minor changes to ensure consistency with AS 4773.

(g) New Appendix I on the relationship between ISO 9223 corrosivity categories and durability class. Also includes solutions for wall ties, connectors and accessories, and lintels and shelf angles, as provided in AS/NZS 2699.1, AS/NZS 2699.2 and AS/NZS 2699.3 respectively.

(h) Changes to Table 10.3 to align with changes made to AS 1170.4.
