These joints are normally made up of an elastomeric structure in which, by a curing process or other technological process, metal profiles are inserted to change, at set points, the stiffness or bearing capacity of the elastomeric structure. There are two main sub-groups depending on the mechanism which is used to obtain the expansion/shrinkage capacity of the joint, namely: by elastic deformation, with shear stress, of appropriately prepared suitable elastomeric areas; by elastic deformation of the elastomeric profiles the designed geometry of which is changed by normally flexural stresses. A characteristic of this type of joints is the presence, at the level of the congested surface, of a series of transverse gaps required for the development of the necessary elastic deformations.

These joints are obtained by opposing two finger-shaped metal elements: each is fixed to its head, thus ensuring, thanks to a suitable interpenetration, continuity of the carriageway in case of expansion/shrinkage. Their static layout can act as a beam on two bearings when the finger rests on both heads or as a shelf when it overhangs a head. A specific device is needed, usually a gutter, to ensure the gap watertightness. Special attention should be paid to the alignment during the installation phase and to the head anchoring, especially in the case of shelf layout. Except for special arrangements, this type of joint permits limited transverse displacements. TIPOLOGIE: SFE 90/65 GP FE C

The Kinematic chain system is a building technology which creates an elastic connection between the decks both longitudinally and transversally thus ensuring a "hinge" behaviour against flexural stresses in the connection area. This system allows all the longitudinal deformations of the deck resulting from shrinkage, creep or temperature changes, to focus on one point, usually the centreline of the engineering structure or by one of the abutments. The Kinematic chain system thus allows to exploit all the advantages offered by continuous structures (seismic behaviour, reduction in the number of joints without giving up those offered by the statically determinate structures consisting of simple beams, design and construction simplicity). It is suitable both for new and existing engineering structures, especially when their seismic adjustment is necessary. It allows to manage longitudinal seismic stresses transferred to the bridge deck/piers interface.
