Keeping Standards up-to-date
Standards are living documents which reflect progress in science. technology andsystems. To maintain their currency all Standards are periodically reviewed and new editions are published. Between editions amendments may be issued.they are using a current Standard which should include any amendments whichmay have been published since the Standard was purchased.
Detailed information about joint Australian/New Zealand Standards can be found byZealand web site at and looking up the relevant Standard in visiting the Standards Web Shop at or Standards Newthe on-line catalogue.
Alternatively both organizations publish an annual printed Catalogue with fulldetails of all current Standards. For more frequent listings or notification of revisions amendments and withdrawals Standards Australia and Standards NewZealand offer a number of update options. For information about these services users should contact their respective national Standards organization.
We also wele suggestions for improvement in our Standards and especiallyambiguities. Please address your ments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the backcover.

PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee BD-006 General Design Requirements and Loading on Structures to supersede in part AS 1170.11989 Minimum design loads on structures Part 1: Dead and liveloads and in part NZS 4203:1992 Code of practice for general structural design and design loadings for buildings and in part AS 2867-1986 Farm structures-Generalrequirements for structural design.
This edition of the Standard includes Amendment No. I which is attached at the end of thedocument. In order to avoid confusion the Amendment has not yet been incorporated into the clauses of the Standard because at the time of publication of the Amendment they hadnot yet been referenced by the BCA.
This Standard is published as a joint Standard (as are also AS/NZS 1170.0 and AS/NZS 1170.2) and it is intended that it is suitable for use in New Zealand as well as inAustralia. However NZS 4203 General structural design and design loadings for buildingsremains current in New Zealand until the publication of all parts (including Part 4: Earthquake action) and for a transition period afterwards.
This Standard will be referenced in the Building Code of Australia by way of BCAAmendment 11 to be Published on 1 July 2002 thereby superseding the previous edition Edition. AS 1170.11989 which will be withdrawn 12 months from the date of publication of this
The objective of this Standard is to provide designers of structures with values representingthe permanent actions likely actions imposed due to use and occupancy and other actionsappropriate to the type of structure for use in structural design.
This Standard is Part 1 of the AS/NZS 1170 series Structural design actions whichprises the following parts each of which have an acpanying Commentary publishedas a Supplement:
AS/NZS 1170.0 Part 0:General principles.1170.1 Part 1:Permanent imposed and other actions.1170.2Part 2:Wind action. 1170.3Part 3:Snow action.1170.4Part 4:Earthquake action.
The Commentary to this Standard is AS/NZS 1170.1 Supp 1 Structural design actionsPermanent imposed and other actionsCommentary (Supplement to AS/NZS 1170.1).
This Standard is not equivalent to ISO 9194:1987 Bases for design of structuresActions due to the self-weight of structures non-structural elements and stored materialsDensity.However it does conform to that Standard (which states Each country in its relevantstandards should use its traditional values which are in the indicated range’). Extracts from the data given in ISO 9194 are provided in the Commentary to this Standard.
This Standard is not equivalent to ISO 2103:1986 Loads due to use and occupancy inin production buildings and warehouses. The philosophy of imposed actions in thisStandard is based on ISO 2103 and ISO 2633. ISO 2103 states that the values it gives arethe lowest values given in the National Standards that were considered. It is not used in Europe or North America. This Standard gives values that are either equivalent to or greaterthan those in ISO 2103. This Standard does conform to ISO 2633 for all values except forthe distributed load for parking which is given as 3.0 kPa in ISO 2633. This higher value is not used in Europe or North America.
(a) Dead and live loads for Australia and New Zealand have been included.Load binations and other general reliability clauses have been removed to the(b) new Standard AS/NZS 1170.0 General principles.(c) The information on movement effects has been included in AS/NZS 1170.0 Supp 1 Commentary on General principles.(p） Permanent and imposed loads from AS 2867 Farm structuresGeneral requirements for structural design have been included.(e) The provision for occasional loading of 4.5 kN for roof trusses or roof structures inindustrial or mercial buildings has been deleted.
