Amended by: AS 3600:2018 Amd 2:2021 Concrete structures
This Standard incorporates Amendment No. 1 (November 2018) and Amendment No. 2 (May 2021). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.
The principal objective of this Standard is to provide users with nationally acceptable unified rules for the design and detailing of concrete structures and members, with or without steel reinforcement or prestressing tendons, based on the principles of structural engineering mechanics. The secondary objective is to provide performance criteria against which the finished structure can be assessed for conformance with the relevant design requirements.
The following list indicates the major differences between this edition and the 2009 edition of AS 3600:
(a) Addition of the following new sections:
(i) Section 14 Design for Earthquakes Actions (formerly Appendix C).
(ii) Section 15 Diaphragms.
(iii) Section 16 Steel Fibre Reinforced Concrete.
(iv) Section 18 Design for Fatigue.
(v) Appendix C Residual Tensile Strength Test for SFRC.
(b) Revision of the following requirements:
(i) Phi factors.
(ii) Maximum steel strength.
(iii) Shear in deep slabs.
(iv) Fire design, including—
(A) axis distances for fire design;
(B) continuous top reinforcement; and
(C) minimum slab thickness.
(v) Modification of models and calculations of—
(A) shrinkage;
(B) creep;
(C) deflections; and
(D) development lengths for higher strength steels.
(vi) Steel shrinkage in areas modelled by strut and tie.
(vii) Punching shear.
(viii) Ductility for pre-cast concrete connections.
(ix) Heating and re-bending bars.
(x) Crack control.
Statements expressed in mandatory terms in notes to figures and tables are deemed to be requirements of this Standard.
The terms ‘normative’ and ‘informative’ are used in Standards to define the application of the appendices to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance.

This Standard sets out minimum requirements for the design and construction of concrete building structures and members that contain reinforcing steel or tendons, or both. It also sets out minimum requirements for plain concrete pedestals and footings.
NOTES:
1: The general principles of concrete design and construction and the criteria embodied in this Standard may be appropriate for concrete structures other than buildings, members not specifically mentioned herein and to materials outside the limits given in Clause 1.1.2.
2: It is intended that the design of a structure or member to which this Standard applies be carried out by, or under the supervision of, a suitably experienced and competent person.
3: For guidance on the design of maritime structures refer to AS 4997.
4: If alternate materials and methods to those prescribed in this Standard are to be used, they would need to be considered as part of the development of a Performance Solution to demonstrate compliance with the relevant Performance Requirements of the National Construction Code (NCC) and be accepted by the relevant building authority.
This Standard is not intended to apply to the design of mass concrete structures.
