This standard sets out rules for the use of simply supported composite steel beam/concrete slab construction in structures, including applications where the slab incorporates profiled steel sheeting and also where the steel beam is concrete encased. For the' purposes of this standard, the concrete slab may be either normal-weight or lightweight concrete as defined in AS 1480.

This standard does not apply to the following structures and materials:

(a)  Dynamically loaded structures.
(b)  Road and railway bridges.
(c)  Material less than 3 mm thick used in the steel beam.
(d)  Steel used in the steel beam for which the value Fx used in design exceeds 450 MPa.
(e)  Cold-formed members used as the steel beam other than those complying with AS 1163.

Notes:

1.  For the design and construction of composite concrete flexural members, see AS 1480; and of composite prestressed concrete flexural members, see AS 1481.
2.  The design and construction of composite slabs using profiled steel sheeting is covered in Part 3 of this standard.
