This edition of the Standard includes Amendment Nos. 1.2and 4.which are attached at theend of the documen.In order to avoid confusion the Amendments have not yet beenincorporated into the clauses of the Standard because at the time of publication of the Amendments they had not yet beenreferenced by the BCA. This Standard is published as a joint Standard (as are also AS/NZS 1170.1 andAS/NZS 1170.2) and it is intended that it is suitable for use in New Zealand as well asAustralia. However NZS 4203 General structural design and design loadings for buildings remains current in New Zealand until the publication of all parts (includingPart 4: Earthquake action) and for a transition period afterwards. For Australia this Standard will be referenced in the Building Code of Australia by way of BCA Amendment 11 to be published on 1 July 2002 thereby superseding in part theprevious Edition AS 1170.11989 which will be withdrawn 12 months from the date ofpublication of this edition. AS 1170.11989 may be used for structures not covered by the Building Code of Australia until an Appendix is developed for inclusion in this Standardby amendment. The objective of this Standard is to provide designers with general procedures and criteriaaccordance with established engineering principles. for the structural design of structures. It outlines a design methodology that is applied in This Standard includes revised Clauses covering load binations (referred to asbinations of actions) and general design and analysis clauses. It does not include values of actions (e.g. values of dead or live loads; referred to as permanent or imposed actions). This Standard is Part 0 of the AS/NZS 1170 series Structural design actions whichprises the following parts each of which will have an acpanying Commentarypublished as a Supplement: Part 1:Permanent imposed and other actionsPart 3:Snow and ice actionsPart 4:Earthquake actions Part 0:General principles Part 2:Wind actions The Commentary to this Standard is AS/NZS 1170.0 Supp 1 Structural design actionsGeneral principles-Commentary (Supplement to AS/NZS 1170.0:2002). This Standard is based on the philosophy and principles set out in ISO 2394:1998 Generalpreparation of national Standards covering the design of structures It includes methods forestablishing and calibrating reliability based limit states design Standards. The terms *normative’ and ‘informative’ have been used in this Standard to define theof a Standard whereas an *informative’ appendix is only for information and guidance.
