Segmental bridge construction combines the advantages of prefabrication, for example the
reduction of construction time and very high product quality, with those of common bridge erecting
methods. Short precast segments are assembled and prestressed to form the complete
superstructure. New methods divide these segments into prefabricated elements to create new
lighter versions of the segments. For this to work, new joint types must be developed which can
ensure the force transfer between the segments. In this paper, several methods, including a new
concept for joining thin-walled pre-fabricated elements, are described. Push-off tests with a
constant lateral force were carried out to assess the shear strength and deformation behaviour. The
main parameters were the joint type (wet joints: plain, grooved, keyed; dry joints), the mortar type,
and the level of lateral force. In this paper, the test results are presented and recalculations with a
design code are shown.
