AS 5216:2021 pdf Design of post-installed and cast-in fastenings in concrete
1.1 Scope and application
1.1.1 Scope
This document specifies minimum requirements for the design of fastenings used to transmit loads to concrete for safety-critical applications.
The fasteners covered in this document are as follows:
(a) Post-installed fasteners:
(i) Mechanical fasteners (e.g. expansion fasteners, undercut fasteners and
concrete screws).
(ii) Chemical fasteners (e.g. chemical fasteners, chemical expansion fasteners).
(b) Cast-in anchor channel with rigid connection (e.g. forged or welded) between the channel
profile and anchor.
This document also includes requirements for the testing and assessment of post-installed and cast-in fasteners to establish the necessary design parameters for use with this document.
The design provisions in this document are relevant to static, quasi-static and seismic loading that may include tension, shear, bending or torsion moments, or a combination thereof.
The design provisions in this document do not apply to the following:
(i) Design of fixtures.
(ii) Design of fastenings for exposure to fire and durability.
(iii) Design of anchor channel for seismic actions.
(iv) Fasteners for lifting, transport and erection (e.g. brace inserts, lifting inserts, etc.), headed
fasteners, ferrules, headed reinforcement and anchorage for prestressing strands.
NOTE For design actions, fastener products, substrates and applications not covered by the scope of this document, the design engineer should seek technical advice from the fastener supplier in relation to the suitability of the selected fastener for the intended application.
C1.1.1 The design theory for fastenings embodied in this document utilizes the tensile strength of concrete and is closely based on the design procedure published in EN 1992-4. The design and installation provisions of this document have been developed on the assumption that materials used and their maintenance ensure that the installed fasteners will fulfil their intended function for the intended life of the structure.
1.1.2 Application
This document relies upon design parameters and product specifications that define a fastener’s suitability for a given application. The testing and assessment of a fastener shall be performed in accordance with the requirements of Appendix A. All necessary design parameters such as characteristic values and product specifications such as geometric and material properties required for Sections 2 to 9 of this document shall be obtained from an assessment report prepared in accordance with Appendix A.
NOTE 1 The design parameters and product specifications required for use with this document may also be obtained from a current European Technical Assessment for the relevant fastener.
NOTE 2 This standard does not cover site testing of fasteners. Guidance on site testing is available in AEFAC Technical Note 05: Guidelines for Site Testing of anchors Vol.1 – Vol.4.
Concrete members shall be composed of normal-weight concrete without fibres and shall conform to the requirements of Clause 2.4.
Supplementary reinforcement and reinforcing steel inserts in chemical fasteners shall have a ductility class type N in accordance with AS/NZS 4671.
Chemical fasteners intended for applications involving sustained tensile loads shall be qualified for
sustained loading applications in accordance with Appendix A.
