Steel Design 3 – Connections

knopen bouwen met staal

This textbook covers the behaviour of connections in steel structures and the design of mechanical fasteners and welds according to EN 1993 (Eurocode 3).

  • Chapter 1 is about the function of connections in a steel structure and describes the different components. It also discusses the most important aspects of design and detailing and the role of the computer in the analysis and design of a steel structure
  • Chapter 2 deals with the most widely used mechanical fasteners in steel structures: bolts in clearance holes (normal holes, oversized holes and slotted holes). The characteristics of bolts are discussed as well as the design rules for checking connections in steel structures with these type of bolts.
  • Chapter 3 deals with the design rules for checking mechanical fasteners when bolts in clearance holes are not allowed or not desirable. This concerns preloaded bolts, fit bolts, injection bolts and pins. The design rules for rivets are also briefly discussed.
  • Chapter 4 gives an overview of the most important welding processes for steel structures and of the most commonly used weld shapes. It then discusses the welding procedures to execute a good welded joint and the methods for detecting and assessing any welding defects. Finally, the design principles of fillet welds and butt welds are covered.
  • Finally, chapter 5 deals with the design of complete connections that are common in steel structures of buildings. A complete connection (mostly called a ‘joint’) comprises all the individual steel parts – such as end plates, stiffeners and angles – and the individual connectors , which together ensure the transfer of forces and moments between the connected elements. It is important how the forces on the individual elements of the connection can be determined from the external forces on the connection.

The author – Jan Stark – is professor emeritus steel structures at Faculty of Civil Engineering and Geosciences, Delft University of Technilogy and an experienced lecturer in the field of steel structures.

‘Steel Design 3 – ‘Connections’ is effective as a textbook for students and as a reference guide to Eurocode 3 for practising structural engineers. The book is part of the ‘Steel Design Books’-series.
