The fatigue behaviour of concrete, and especially of high-strength concrete, has become more important for the design of structures due to more slender structures, which are more sensitive to fatigue loading, or due to wind turbines, which are typically exposed to high-fatigue loading. The fatigue behaviour of a high-strength concrete was investigated within a research project with respect to the influence of maximum stress level, loading frequency and waveform. The investigations were focused on low-cycle-fatigue. The influence on numbers of cycles to failure and on the developments of strain and stiffness were systematically analysed. Selected results are presented in this paper. For the three influences investigated the results show certain systematologies in the change of strain and stiffness parameters with respect to the change in number of cycles to failure.
