This book is the second in a series of joint SCI-ECCS publications. It will help provide UK engineers and designers with a better understanding of the design principles in the European Code of Practice for the Design of Steel Structures (EN 1993 – Eurocode 3), and the individual Part 1.8 (EN 1993-1-8) for the design of steel joints, in particular. Reference will also be made to the associated Eurocodes for concrete (EN 1992 – Eurocode 2), and earthquake engineering (EN 1998 – Eurocode 8).

This book details the basic concepts and the design rules included in EN 1993-1-8. Attention should be paid to the behaviour of the joints when designing a steel structure, in order to assure the global safety of the construction, and to control the overall cost, including fabrication, transportation and erection. Therefore, in this book, the design of the joints themselves is covered in detail, but aspects of the selection of the most appropriate configuration of joint, and integration of the joints into the analysis and the design process of the whole construction, are also fully covered.

Connections using mechanical fasteners and welds are discussed, and joints that are simple, moment-resisting, and in lattice girders are considered. Various joint configurations are treated, including beam-to-column, beam-to-beam, column bases, and beam and column splice configurations, under different loading situations (axial forces, shear forces, bending moments and their combinations). The book also briefly summarises the available knowledge relating to the application of the Eurocode rules to joints under fire, fatigue, earthquake, etc., and to joints in a structure subjected to exceptional loadings, where the risk of progressive collapse has to be mitigated.

Finally, there are some worked examples, plus references to already published examples and to design tools, which will provide practical help to designers.
