PREFACE
Committee BD-006 General Design Requirements and Loading on Structures to supersede This Standard was prepared by the Joint Standards Australia/Standards New Zealandin 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 Farm structuresGeneralrequirements for structural design.
This Standard is published as a joint Standard (as are also AS/NZS 1170.0 andAS/NZS 1170.2) and it is intended that it is suitable for use in New Zealand as well as in Australia.However NZS4203 General structural design anddesign loadings forbuildingsremains current in New Zealand until the publication of all parts (includingPart 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 thereby superseding the previous edition AS 1170.11989 which will be withdrawn 12 months from the date of publication of this Edition.
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 which prises the following parts each of which have an acpanying Commentary publishedas a Supplement:
AS/NZS
1170.0 General principles.
1170.1Permanent imposed and other actions.
1170.2Wind action.
1170.3 Snow action.
1170.4 Earthquake action.
Permanent imposed and other actions-Commentary (Supplement to AS/NZS 1170.1). The Commentary to this Standard is AS/NZS 1170.1 Supp 1 Sructural design actions-
This Standard is not equivalent to ISO 9194:1987 Bases for design of structuresActionsdue to theself-weight ofstructuresnon-structuralelements and storedmaterialsDensity. 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 fromthe data given in ISO 9194 are provided in the Commentary to this Standard.
This Standard is not equivalent to ISO 2103:1986 Loads due fo use and occupancy inin production buildings and warehouses. The philosophy of imposed actions in thisthe lowest values given in the National Standards that were considered. It is not used inEurope 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 fornot used in Europe or North America.
This edition incorporates the following principal changes from the previous edition:
(a)Dead and live loads for Australia and New Zealand have been included.(b)Load binations and other general reliability clauses have been removed to thenew 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.(d) Permanent and imposed loads from AS 2867 Farm structuresGeneral requirementsfor 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.
The term ‘normative’ has been used in this Standard to define the application of the appendix to which it applies. A *normative’ appendix is an integral part of a Standard.

SECTION1 SCOPE AND GENERAL
1.1 SCOPE
This Standard specifies permanent imposed，liquid pressure. ground water rainwaterponding and earth pressure actions to be used in the limit state design of structures and parts of structures.
1.2APPLICATION
This Standard shall be read in conjunction with AS/NZS 1170.0.
This Standard may be used as a means for demonstrating pliance with the Requirementsof Parnt B1 of the Building Code of Australia.
1.3DETERMINATION OFDESIGNACTIONS
For the actions covered by this Standard values for use in design shall be appropriate forthe type of structure or structural element its intended use and exposure to such actions.
The determination of values in accordance with Sections 2 to 4 shall be deemed to satisfythis Clause.
