Scope and general

This Standard sets out minimum requirements for the design, detailing and construction of composite steel-concrete members (beams, columns, slabs, joints) in buildings.

This Standard does not cover the design of composite beams and columns-

(a) where the elements of the steel section are less than 3 mm thick or the value of the yield stress (f_y) assumed in design exceeds 690 MPa;

(b) where the concrete characteristic compressive strength at 28 days is outside the range of 20 MPa to 120 MPa; or

(c) for road or railway bridges (see NOTE).

NOTE: For the design of composite bridge beams, reference should be made to AS/NZS 5100.6.
