Moment-Resisting Joints

Moment‐resisting joints is a general term used to cover all joints which transfer significant bending moments between the connected members, but also shear and/or axial forces. These joints may be rigid or semi‐rigid, in terms of stiffness, and may exhibit a full or a partial strength resistance level. This chapter first addresses the characterisation of the mechanical response of individual components covered by EN 1993‐1‐8. Then, it discusses the assembly procedure problem, successively in terms of resistance, stiffness and deformation capacity. The chapter presents the application of the component approach to specific joints. it considers the following joint configurations: steel beam‐to‐column, beam‐to‐beam and beam splices; steel column splices; and column bases. In EN 1993‐1‐8, components are characterised by means of three specific design properties: the elastic stiffness; the plastic resistance; and the (plastic) deformation capacity.
