AS 1684.4, 4 Edition – Residential timber-framed construction, Part 4: Simplified – Non-Cyclonic Areas

This Standard 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 by the Building Code of Australia and within the
limitations given in Clause 1.4. The provisions of the Standard also apply to alterations and
additions to these buildings.

This Standard also provides building practice and procedures that assist in the correct
specification and determination of timber members, bracing and connections, thereby
minimizing the risk of creating an environment that may adversely affect the ultimate
performance of the structure.

This Standard may also be applicable to the design and construction of other classes of
buildings where the design criteria, loadings and other parameters applicable to those
classes of building are within the limitations of this Standard.

NOTES:
1 See AS 1684.1 for details of design criteria, loadings and other parameters.

2 Whilst this Standard may be used to design Class 10 buildings, less conservative levels of
design for this building class may be permitted by building regulations and other Australian
Standards.

3 Advisory information for the construction and specifications of timber stairs, handrails and
balustrades, is provided in the FWPA’s publication (see the Bibliography).
Member Span Tables are given in Appendix A.
