During March 2010, Australian Emeritus Professor Greg Hancock presented a course on the design of cold-formed steel structures to the Australian code AS/NZS 4600:2005 in South Africa. This was arranged by the SA Institute of Steel Construction, as the SA Bureau of Standards is in the process of adopting the Australian standard to replace the outdated SANS 10162:2. The notes covers his introduction to cold-formed steel design and a design example of a simply supported purlin under uplift. It explains the ‘direct strength’ method of design of cold-formed beams /purlins which simplifies the cold-formed design methodology, followed by a design example of a cold-formed lipped channel column - illustrating the advantage of the use of the direct strength design method. In conclusion various fastening techniques are covered, supported by the appropriate design calculations. These course notes can be ordered from the Institute.

In the course notes, references are made to his 240-page book on the subject “Design of Cold-formed Steel Structures (to AS/NZS 4600:2005)”. It covers materials and the effects of cold working; buckling modes of thin-walled members; stiffened and un-stiffened compression elements; beams, purlins and bracing; webs; compression members; combined axial loading and bending, and the ‘direct strength method’. The Institute arranged with the Australian Steel Institute to distribute the book in South Africa.

Both these publications are strongly recommended for cold-formed steel designers.
