This book examines the plastic design and behaviour of main frames--both low-rise industrial and agricultural, and multistorey. Representative topics, such as member and frame stability and restraints and connections, are explained in clear and detailed presentations, and will interest practitioners and students alike. Explanations are buttressed by many diagrams and numerous worked examples. Published on behalf of the Steel Construction Institute, the book was written by Professor J.M. Davies of the University of Manchester, and Brian Brown, chartered structural engineer.
