Abstract:
Fatigue limit state design is dominant design consideration in offshore and onshore wind turbine concrete structure design. Generally, fatigue life prediction models are developed based on the data from the experimental tests on plain concrete cylinders or prisms. Therefore, there is a need for more exploration and testing to consider different material conditions. The fatigue model's prediction and existing experimental data vary by a few folds. In this study, the effect of concrete saturation, and the presence of longitudinal reinforcement have been explored to better understand the behavior of the concrete, as well as shed light on the differences between model predictions and actual behavior. Concrete printing techniques are improving, and they are some suggested possible uses in offshore wind structures. Thus, a few 3D-print concrete cylinders are tested under fatigue loading to have an insight into its behavior and difference between 3D-print concrete and casted plain concrete.
