This report prepared by Greg Hancock investigates alternatives for the continued development and harmonisation of AS 4100 with international standards particularly AISC 360 and BS EN 1993-1. The advantages and disadvantages of using these specifications, standards or parts of these and the issues related to adoption of these standards in whole or in part in Australia are discussed. Costs and benefits of the alternatives are examined, as well as financing and alternative means of publication. Steel Construction journal, vol. 44, no.2, Jun 2011.
