The Standard provides minimum requirements for the selection, design and specification of pot, elastomeric and mechanical bearings, plane sliding contact surfaces and deck joints for use in bridge structures. The Standard supersedes the Austroads Bridge Design Code, ABDC-1992 (HB 77.4) and AS 1523-1981. It is also a useful reference and guide for the selection, design and specification of bearings in buildings and other structures.Guidelines for bearings subject to uplift are included.PTFE lined aluminium alloy spherical bearings are not included due to their low horizontal load capacity and concern about the extrusion of the bonded PTFE rotating layer.While the preferred types of bearings for use in bridges are elastomeric and pot bearings, the Standard does not preclude the use of other types of bearings.There are also new appendices covering standard laminated elastomeric sizes, the testing of elastomer, manufacturing tolerances, and the testing of completed bearings.For further information, see NAASRA (1976) (Ref. 1).
