AS 3600:2018 SUP 1, 4th, 2022 – Concrete structures – Commentary (Supplement 1 to AS 3600:2018)

AS 3600 Supplement was prepared by Standards Australia Committee BD-002, Concrete Structures,
to supersede AS 3600—2009 Supp 1:2014, Concrete structures—Commentary (Supplement to
AS 3600:2009).
The objective of this document is to provide commentary to assist in the interpretation of the provisions
of AS 3600:2018, Concrete structures, by —
(a) providing background reference material to the requirements in the Standard;
(b) indicating the origin of particular requirements;
(c) indicating departures from previous practice due to changes that have occurred in
construction practice and theory since the previous edition of the Standard was published; and
(d) explaining the application of certain clauses.
In this document, AS 3600:2018 is referred to as “the Standard” or “the 2018 edition of the Standard”
while this document is referred to as “this document”. The numbers and titles of sections and clauses
used in this document align with those in the Standard except that the numbers are prefixed with
the letter “C”. The figures in this document are numbered according to the clause in which they are
referenced and also carry the “C” prefix. Therefore references to sections, clauses, tables, figures,
equations and appendices that are not identified by the prefix “C” refer to the Standard unless
indicated otherwise.
Documents referenced in the text and documents recommended for further reading are listed at the
end of the applicable section or appendix to which they relate.
While it is intended that this document be read in conjunction with the Standard, it does not form an
integral part of the Standard.
The opportunity has also been taken to include improvements suggested since the last edition by users.
Like the Standard itself, this document is an ongoing work-in-progress. Suggestions for improvements
to both the Standard and to this document, in regard either to content or to clarity of wording, are
therefore welcomed.
