Eurocode 3 - Design of joints
The following terms and definitions apply:
– basic component (of a joint): Part of a joint that makes a contribution to one or more of its structural properties.
– connection: location at which two or more elements meet. For design purposes it is the assembly of
the basic components required to represent the behaviour during the transfer of the relevant internal
forces and moments at the connection.
– connected member: any member that is joined to a supporting member or element.
– joint: zone where two or more members are interconnected. For design purposes it is the assembly of
all the basic components required to represent the behaviour during the transfer of the relevant internal forces and moments between the connected members. A beam-to-column joint consists of a web panel and either one connection (single sided joint configuration) or two connections (double sided joint configuration).
– joint configuration: type or layout of the joint or joints in a zone within which the axes of two or more inter-connected members intersect.
– rotational capacity: the angle through which the joint can rotate without failing.
– rotational stiffness: the moment required to produce unit rotation in a joint.
– structural properties (of a joint): resistance to internal forces and moments in the connected members, rotational stiffness and rotation capacity.
– uniplanar joint: in a lattice structure a uniplanar joint connects members that are situated in a single plane.
