Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.

Detailed information about Standards can be found by visiting the Standards Web Shop at www.standards.com.au and looking up the relevant Standard in the on-line catalogue.

Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Global Standard, has a full listing of revisions and amendments published each month.

Australian Standards^TM and other products and services developed by Standards Australia are published and distributed under contract by SAI Global, which operates the Standards Web Shop.

We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Contact us via email at mail@standards.org.au, or write to the Chief Executive, Standards Australia, GPO Box 476, Sydney, NSW 2001.

GENERAL INTRODUCTION

The 45 Supplements give tables of maximum span in their various structural applications for a range of commonly supplied timber sections in wind classifications C1, C2, and C3, provided they have been mechanically stress-graded or visually stress-graded in their unseasoned or seasoned condition in accordance with the appropriate Australian Standard.

The Supplements shall be read in conjunction with the Standard, and the tables of span for the various members shall apply only where the structures, in which they are used, are constructed in accordance with the clauses given in the Standard.

NOTES:

Maximum bearer spans supporting roof loads are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m², a maximum total tile roof, framing and ceiling mass of 90 kg/m² and a maximum flooring mass of 40 kg/m². For guidance on determination of roof mass refer to Appendix B.
Cantilevers shall not exceed 50% of actual backspan.
Minimum bearing length = 50 mm at end supports and 100 mm at internal supports for continuous members.
Multiple members shall be nailed together as per Clause 2.3.
For design parameters refer to Figure 4.6.
Where loadbearing walls are supported at right angles to bearer within the bearer span reference should be made to Clause 4.3.1.5.
Where bearers support roof point loads, reference should be made to Clause 4.3.1.6.
