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.

Scope

This Standard sets out minimum requirements for the design, detailing and construction of simply supported composite beams composed of a steel beam and a concrete slab interconnected with shear connectors, including applications where the slab incorporates profiled steel sheeting, as defined in Clause 1.2.

This Standard does not cover the design of composite beams –
(a) where the elements of the steel beam are less than 3 mm thick or the value of the yield stress (fyb) assumed in design exceeds 450 MPa (see Note 1);
(b) where the strength grade of the slab concrete exceeds 40 MPa;
(c) where the slab is precast or prestressed;
(d) with negative design moments (see Note 2);
(e) subjected to dynamic loads;
(f) for road or railway bridges (see Note 3); or
(g) for fatigue.

NOTES:
1 This does not preclude the use of steels with a minimum yield strength greater than 450 MPa.
2 For the design of composite beams with negative design moments reference may be made to BS 5950:3:1990, Code of Practice for Design of Simple and Continuous Composite Beams.
3 For the design of composite bridge beams, reference should be made to the AUSTROADS Bridge Design Code, or the ANZRC Railway Bridge Design Manual as applicable.
