AS/NZS 5131:2016

AS/NZS 5131, 1st – Structural steelwork – Fabrication and erection

AS/NZS 5131 sets out minimum requirements for the construction of structural steelwork
involving fabrication, preparation of steel surfaces for corrosion protection, corrosion
protection comprising painting and galvanizing, erection and modification of steelwork. It
applies to complete structures, individual members and components, and manufactured
components pre-fabricated for inclusion in a steel structure.
This Standard specifies requirements for the construction of structural steelwork produced
from the following:

(a) Hot-rolled and welded structural steel sections, flat bars and plates including those
with a yield stress used in design of 690 MPa or less, which comply with one of the
material Standards listed in Section 2 and which were designed using AS 4100 or
AS 5100.6 or NZS 3404.

(b) Cold-formed structural hollow sections, including hollow sections manufactured by
welding, which comply with AS/NZS 1163 and which were designed using AS 4100
or AS 5100.6 or NZS 3404.

(c) Weathering steel members and components complying with AS/NZS 3678 and
AS/NZS 1594.

(d) Steel members in composite steel and concrete structures designed using AS 2327.1
or AS 5100.6 or NZS 3404, including beams, columns, composite slabs and decking.

(e) Cold-formed purlin and girt members and decking designed using AS/NZS 4600.

This Standard applies to all types of buildings, general structures, crane runway girders,
monorails, roadway bridges, rail bridges and pedestrian bridges. Its application includes
complete structures, individual members and manufactured components subject to seismic
actions or to fatigue.
Some requirements are expressed in terms of construction categories.
NOTE: Guidance on construction categories is provided in Appendix C.
Provisions on inspection of welding and bolting applying to New Zealand only are covered
in Appendix I.
