AS 1684.2-1999

Specifies requirements for building practice and for the selection, placement and fixing of the various structural elements used in the construction of timber-framed Class 1 and Class 10 buildings, as defined in the Building Code of Australia, for non-cyclonic areas. It also sets out building practice procedures, which are given to assist in the correct specification and design of timber members, bracing and connections thereby minimizing the risk of creating an environment that might adversely affect the ultimate performance of the structure. Appendices specify a method of interpolation for Span Tables in the Supplements, and an alternative procedure for determining racking forces. Guidance is given on mass of roof, timber natural durability, moisture content, timber species and properties. Some examples are also included. IMPORTANT NOTE: The 45 supplements, giving different wind classifications and stress grades of various timbers, form an integral part of the Standard. They are included in a CD-ROM, attached to this Standard. When in a set, these Supplements are available as individual documents within the set.
