Transmission of longitudinal shear forces in composite constructions with concrete dowels is well known regarding static loads. This paper contributes to the influence of cyclic loading on concrete dowels in composite constructions, in order to arrive at an efficient and mechanical suitable shear connection, which is applicable for both bridge and industrial constructions. The relevant influence factors on the cyclic load bearing and deformation behaviour of cyclic loaded concrete dowels were systematically analysed in consideration of previously pub-lished research results and an own experimental investigations. Calculation specifications for the cyclic slip progress and the cyclic characteristic dowel curve have been derived conse-quently. Based on these specific parameters, deformation states for any load cycle rate of a concrete dowel is possible to be quantified. The evaluation of endurance of the steel recess of a concrete dowel was achieved with a modification of the local stress concept. The modifi-cation was the implementation of the derived calculation specification for the deformation in the process of the local stress concept and the identification of the relevant damage parame-ters. The derived calculation principles were all verified on experimental studies and are valid for the whole underlying spectrum. Consequently, the present paper makes a contribution to realistic calculations of cyclic loaded concrete dowels.
