This standard applies to the design, fabrication, erection, repair and alteration of steel-work in structures, including foot and service bridges.
The standard does not apply to the following structures and materials:
(a) Road and railway bridges.
(b) Material less than 3 mm thick.
(c) Steel for which the value FY used in design exceeds 450 MPa.
(d) Cold-formed members other than those com-plying with AS 1163.
NOTES:
1. The use of cold-formed steel sections in structures is covered by AS 1538. Reference should also be made to Addendum No 1 to BS 449 (PD 4064), and the AISI* Cold-formed Steel Design Manual.
2. Packings may be of any thickness.
