Concrete fatigue of composite constructions with rib shear connectors

Rib shear connectors are gaining increasingly attention in the field of composite constructions. Especially bridge constructions, rib offer many advantages compared to conventional such as headed studs. In order describe load-bearing behaviour under cyclic loading, successively increasing slip resulting from loading must be taken into account. The latter leads growth relative displacements along joint and thus, degradation previously rigid connection. This effect rearrangements internal forces between partners through which load bearing capacity structure alter. this article results experimental investigations on two single Push-Out-Tests (sPOT) one full-scale girder test regarding interconnection presented analysed. investigated subjected a comparable history that sPOT. give insight effects connection, seen sPOT, overall girders.
