Abstract:
In most cases, fatigue limit state design is the 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. The fatigue model’s prediction and existing experimental data vary by a few folds. Investigating the previous experimental datasets has raised the suspicion that the variation in strength among cylinders from the same batch can be the main influential parameter on high variation in fatigue capacity results. In order to eliminate or reduce this effect, a new method of compressive fatigue testing has been proposed by authors and has been used in 3 different concrete batches and showed promising results. A new testing campaign will start at Tufts University to further investigate this method. The method and results would be presented at the upcoming ACI convention.
