scope:

This Standard sets out minimum requirements for the design, fabrication and erection of the structural steelwork in bridges. Wrought and cast iron structures may be checked in accordance with this Standard, using the appropriate material properties and capacity reduction factors.

The Standard also includes requirements for the design of other steel components of bridges including steel piers, steel railings, sign structures, and structural interaction between steel and concrete composite members.

APPLICATION

The requirements for bridges, members and materials specified in Items (a) to (d) of Clause 1.2, and for new and unusual bridge types shall be designated by the relevant authority.

In the design of steel-concrete composite members, the general requirements of AS 5100.5 pertaining to the design of concrete shall apply, where relevant, in addition to the requirements of this Standard.

NOTE: In New Zealand, the concrete structures design may be designated by the relevant authority.

The design of structural elements using non-ferrous metals such as aluminium alloys is not covered in this Standard. Where such components are to carry calculated stress, the applicable specification to be used in their design shall be designated by the relevant authority.
