While giving a thorough overview of the structural behaviour and design of cold-formed tubular members and connections, this book also considers the special characteristics of cold-formed steel hollow sections such as rounded stress-strain material behaviour, variation of yield stress around the section, and unique failure modes. The following topics are explored in systematic detail: members subjected to bending, compression, combined bending and compression, local buckling under concentrated force, effect of bending on bearing capacity, tension members and welds in thin-walled tubes, welded connections subjected to fatigue loading, effect of concrete-filling and large-deformation cyclic loading on limiting width-to-thickness ratios, fatigue design using hot spot stress method, bolted moment end plate connections and plastic design of portal frames. This book not only summarises the research performed to date on cold-formed tubular members and connections but also provides design examples in accordance with both the Australian Standard AS 4100 and the British Standard BS 5950 Part 1. It is an ideal reference companion for structural engineers, researchers and university students interested in tubular steel structures. Book jacket.
