AS/NZS 2327:2017

Sets out minimum requirements for the design, detailing and construction of simply supported composite beams composed of a steel beam interconnected to a concrete slab by shear connectors, including applications in which the slab incorporates profiled steel sheeting. Covers strength and serviceability design for flexure, transverse and longitudinal shear and their interdependence as well as design for fire-resistance. Permits the use of partial shear connection and a wider variety of steel beam sections and shear connector types than previously allowed. Includes detail requirements for construction loads, slab reinforcement and sheer connector positioning, along and transverse to the beam length. Also included are a number of appendices containing design flowcharts and other helpful information.

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 (fy) assumed in design exceeds 690 MPa;(b) where the concrete characteristic compressive strength at 28 days is outside the range of 20 MPa to 100 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 the AUSTROADS Bridge Design Code.
