The Australian/New Zealand Standard AS/NZS 4600 has been revised based in part on the latest edition of the North American Specification AISI S100:2016 and partly based on the latest research in Australia and New Zealand. The Direct Strength Method (DSM) of design has undergone substantial research since the 2005 edition of AS/NZS 4600 and this research is now incorporated in the revised edition. The new areas in the DSM include shear, combined bending and shear, combined bending and compression, sections with holes and inelastic reserve capacity. Further, the prequalified sections now include most sections with longitudinal web and flange stiffeners based in part on Australian research on high strength sections with multiple stiffeners.
