This Standard covers the design, manufacture and methods for testing prototypes of prestressing anchorages, for establishing performance for use in prestressed concrete.
Scope
This Standard specifies minimum requirements for the—
(a) materials;
(b) manufacture; and
(c) methods of establishing the static or cyclic load performance, of prestressing anchorages and couplings intended for retaining the prestressing forces induced in wire, strand, or bar tendons and for transferring those forces to concrete members.
This Standard does not apply to the calculation of the stresses, or to the design of the concrete zones in which anchorages are embedded (see AS 3600 or NZS 3101.1).
Appendix B of the Standard is directly applicable to single tendon anchorages commonly employed by precast concrete manufacturers in pretensioning operations and multiple reuse of barrels and wedges.
Where multiple re-use of wedges occur, careful attention to the condition of the wedge teeth is essential. This is a management responsibility and beyond the scope of this Standard. NOTE: Means for demonstrating compliance with this Standard are given in Appendix A.
