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.
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.
1.3  Terms and definitions
For the purpose of this document, the following terms and definitions apply.1.3.1 action set of concentrated or distributed forces acting on a structure (direct action), or deformation imposed on a structure or constrained within it (indirect action) 1.3.2 anchor headed component of anchor channel Note 1 to entry: In Australian practice, a fastener installed in concrete may be referred to as an “anchor”, such as “mechanical anchor” and “chemical anchor”. For clarity in this document the term “anchor” is reserved for the headed component of the anchor channel. 1.3.3 anchor channel fastener made of profiled steel element with two or more rigidly connected anchors that are installed into position prior to the casting of concrete (see Figure 1.3(B)) 1.3.4 base material material in which the fastener is installed 1.3.5 bond failure mode of failure for chemical fasteners characterized by pull-out of the fastener caused by either separation at the interface of the bonding compound and the embedded steel element or between the bonding compound and the base material 1.3.6 capacity reduction factor factor used to multiply the nominal capacity to obtain the design capacity 1.3.7 cast-in fastener fastener that is installed into position prior to the casting of concrete (see Figure 1.3(B)) 1.3.8 channel bolt screw or bolt positioned in the steel profile of the anchor channel that is used to connect an element to the anchor channel 1.3.9 characteristic edge distance distance required between the free edge of a concrete member and the centre-line axis of the fastener in order to develop the characteristic strength of the fastener
