Abstract

Connections and joints constitute a very important part of structural steelwork, to be met during its fabrication and erection. This chapter introduces the basis of design for mechanical and welded connections and joints. It gives the specifications of the different types of bolts and accessories, the geometrical properties for bolted assemblies and the installation of bolts. It then introduces the main categories of bolted connections, whether bearing or slip resistant at SLS or ULS when subjected to shear forces and non-preloaded or preloaded when subjected to tension forces. For these types of bolted connections and for connections with pins it gives the Eurocode 3 provisions to determine the design resistances and preforming the relevant checks. It presents welding connections, providing technological information on welding methods, residual stresses and welding deformations. It defines the types and geometric properties of welds giving the design resistances of fillet, butt and plug welds. It then gives the design of joints subjected to shear forces, whether long lap joints, or splices of members, providing elastic and plastic methods for groups of fasteners. Subsequently it introduces the T -stub as the basic element of joints subjected to tension or compression forces. It then provides the classification of joints, whether by stiffness or by strength. It finally presents design methods for typical joints, such as beam-to-column joints, welded or bolted, column bases, or hollow section joints.
