To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important there
5、fore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto. Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the mag
6、azine The Australian Standard, which subscribing members receive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notificatio
7、n of any inaccuracy or amibuity found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate action taken. ?

Amendment No. 11992 includes the following major changes: (a)Strength of steels complying with AS 1163 and AS/NZS 159
16、4. (Table 2.1.) (b)Shear buckling capacity for stiffened web. (Clause 5.11.5.2.) (c)Bearing buckling capacity. (Clause 5.13.4.) Amendment No. 21993 includes the following major changes: (a)Shear and bending interaction method. (Clause 5.12.3.) (b)Minimum area for the design of intermediate transvers
17、e web stiffeners. (Clause 5.15.3.) (c)Section capacity of members subject to combined actions. (Clause 8.3.) (d)Strength assessment of a butt weld. (Clause 9.7.2.7.) (e)Fatigue. (Section 11.) Amendment No. 31993 includes the following major changes: (a)Compressive bearing action on the edge of a web
18、. (Clause 5.13.) (b)Section capacity of members subject to combined actions. (Clause 8.3.) (c)In-plane and out-of-plane capacity of compression members. (Clauses 8.4.2.2 and 8.4.41.) (d)Strength assessment of a butt weld. (Clause 9.7.2.7.) (e)Earthquake. (Section 13.) Amendment No. 4 includes the fo
19、llowing major changes: (a)Strengths of steels complying with AS/NZS 3678, AS/NZS 3679.1 and AS/NZS 3679.2. (Table 2.1.) (b)Minimum edge distance of fasteners. (Clause 9.6.2.) (c)Permissible service temperatures according to steel type and thickness. (Table 10.4.1.) (d)Steel type relationship to stee
20、l grade. (Table 10.4.4.) (e)Welding of concentrically braced frames for structures of earthquake Design Category D and E. (Clause 13.3.4.2.) The terms normative and informative have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an i
