AS 4773.1:2010 PDF Download

AS 4773.1:2010 is a standard that specifies the design and specification requirements for masonry in small buildings. This standard applies to buildings of Class 1 and Class 10a, as defined by the Building Code of Australia (BCA), where the leaf thickness of the masonry is 90 mm or greater. The walls in these buildings should have lateral support from a roof or floor structure, except for certain exceptions such as parapets, chimneys, and cantilevers.

The standard also specifies that the masonry walls should be supported on concrete slabs or footings complying with AS 2870, the standard for residential slabs and footings, or suspended slabs complying with AS 3600, the standard for concrete structures. The design should adhere to the geometric limitations described in Clause 1.2.3 of the standard.

It is important to note that this standard does not cover acoustic and energy efficiency requirements, the design of attachments such as basketball hoops and satellite dishes, and structures that need to be designed for earthquake actions. For acoustic and energy efficiency requirements, reference should be made to the BCA. For applications outside the scope of this standard, the masonry should be designed in accordance with AS 3700. Appendix A provides the basis of design and assumptions used in the preparation of this standard.
