AS/NZS 2699.1:2000 Built-in components for masonry construction, Part 1: Wall ties
Standards Australia/Standards New Zealand
Supersedes: AS 2699-1984 Wall ties for masonry construction
This Standard is the first of a three-part series on masonry wall ties, connectors and
accessories, and lintels and shelf angles. The series comprises the following:
AS/NZS
2699 Built-in components for masonry construction
2699.1 Part 1: Wall ties
2699.2 Part 2: Connectors and accessories
2699.3 Part 3: Lintels and shelf angles (durability requirements)
The objective of this Standard is to provide manufacturers with requirements for the
classification of wall ties into three duty ratings. Type A cavity wall ties and veneer wall ties
are classified according to characteristic strength only. Type B seismic-resistant veneer ties
are classified according to stiffness and characteristic strength which are functions of
serviceability, ultimate strength and ductility or toughness. All ties are classified for their
corrosion resistance. Provisions are also included for remedial (retrofitted) ties.
Test methods are given for determination of —
(a) resistance to water transfer;
(b) characteristic strength and stiffness; and
(c) corrosion resistance.
The types and spacings of ties necessary to meet design requirements are specified in
AS 3700, Masonry structures, and NZS 4210, Code of practice for masonry construction
materials and workmanship.
The terms ‘normative’ and ‘informative’ have been used in this Standard 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.
Notes to clauses in this Standard are for information and guidance only and compliance with
them is not a requirement of the Standard.
Originated in Australia as AS INT 324-1953. Revised and redesignated as AS 2699-1984. Originated in New Zealand as NZS 4210:1989. AS 2699-1984 and part of NZS 4210:1989 jointly revised and redesignated as AS/NZS 2699.1:2000.
This Standard specifies the requirements for wall ties
for use in tying together —
(a) the leaves of cavity masonry walls;
(b) masonry veneer walls and load-bearing frames; and
(c) masonry veneer walls against a strong backing wall.
NOTES:
1: AS/NZS 2699.2 specifies the durability performance and test procedures for structural
performance of connectors and accessories used in masonry construction.
2: AS/NZS 2699.3 specifies the requirements for durability of lintels and shelf angles.
3: This Standard gives categories of wall ties, and classifies wall ties by characteristic strength
and durability and, where applicable, characteristic stiffness.
4: The durability classifications employed in this Standard are compatible with the environments
specified in AS/NZS 2312, NZS 3604 and AS 3700.
5: Design and installation of wall ties are specified in AS 3700, NZS 4210 and NZS 4230.
This Standard applies to ties used in masonry described in AS 3700, NZS 4210 and
NZS 4230, including those used in thin-jointed masonry (for example, autoclaved aerated concrete (AAC) blockwork).
