AS 4055—2006

This Standard was prepared by the Standards Australia Committee BD-099, Wind loads for housing to supersede AS 4055—1992.
This Standard will be referenced in the Building Code of Australia 2006 edition (BCA 2006), thereby superseding in part the previous edition, AS 4055—1992, which will be withdrawn 12 months from the date of publication of this edition.
The objective of this Standard is to provide designers, builders and manufacturers of building products that are affected by wind loading with a range of wind speed classes that can be used to design and specify such products for use in housing that are within the limitations in this Standard.
This edition differs from the previous edition as follows:
(a) Wind speeds are specified for the serviceability and ultimate strength/stability limit states only. Permissible stress has been omitted.
(b) The Standard has been updated to reflect the latest technical knowledge on wind forces as represented by the 2002 edition of AS/NZS 1170.2.
© The table of classes for site conditions has been updated.
(d) Pressure factors have been made normative and calculation methods given for determining pressures and forces.
(e) New racking tables have been included in limit states format.
(f) A more detailed commentary has been added (Appendix A) to clarify the relationship of this Standard to AS/NZS 1170.2 and to give background to some of the clauses.
The term ‘informative’ has been used in this Standard to define the application of the Appendix to which it applies. An ‘informative’ appendix is only for information and guidance.
Notes to the text contain information and guidance. They are not an integral part of the Standard.
