An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by Intertek Inform as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.

Provides requirements for determining wind actions for use in structural design. It includes revised sections on combination factors and cantilevered roofs and new provisions for torsion and windborne debris testing. It also provides for the treatment of doors as openings, and increased local pressure factors. Wind speeds and direction factors are given for regions in Australia and New Zealand. Factors are provided to cover the environment around the structure, the geometry of the structure and the dynamic interaction of the structure with the wind.

This Standard sets out procedures for determining wind speeds and resulting wind actions to be used in the structural design of structures subjected to wind actions other than those caused by tornadoes.The Standard covers structures within the following criteria:(a) Buildings less than or equal to 200 m high.(b) Structures with roof spans less than 100 m.(c) Structures other than offshore structures, bridges and transmission towers.NOTES:1 This Standard is a stand-alone document for structures within the above criteria. It may be used, in general, for all structures but other information may be necessary. 2 Where structures have natural frequencies less than 1 Hz, Section 6 requires dynamic analysis to be carried out (see Section 6).3 In this document, the words ‘this Standard’ indicate AS/NZS 1170.2, which is regarded as Part 2 of the AS/NZS 1170 series of Standards (see Preface).4 Further advice should be sought for geometries not described in this Standard, such as the roofs of podiums below tall buildings.
