AS/NZS 2041:1998

Provides manufacturing requirements, design methods and installation requirements for structures assembled from curved corrugated metal sheet or plates. Structures covered include pipes, pipe-arches, arches and special shapes. Design methods are based on ring compression and buckling failure modes. Information is given on durability. Considerations include handling stiffness, fill requirements and compaction. Tables of maximum and minimum cover are given as a guide to structure selection.

This Standard specifies requirements for materials, manufacture, design methods and installation of buried corrugated metal pipes, pipearches, arches and special shapes comprising bolted corrugated metal sheets or plates manufactured within the limits given in Table 1.1 and Section 2. It deals only with those structures in which the sheets or plates have circumferential corrugations running normal to the longitudinal axis of the structures.The Standard does not cover the design of arch footings, rib stiffening or those structures covered by AS 1761, AS 1762, AS 3703.1 and AS 3703.2.NOTES:1 Ordering guidelines are detailed in Appendix A. Information on the means of demonstrating compliance with this Standard for manufacture of the metal components is given in Appendix B. Information on the assessment of durability is given in Appendix C.2 Buried corrugated metal structures withstand applied loads through the interactive behaviour of the flexible metal ring and the surrounding soil envelope. The stiffness of both of these materials is considered during design.
