Abstract
Fatigue verification becomes decisive for the design of slender structures of high-strength concretes. But there is a lack of knowledge regarding the fatigue behaviour, especially for wet environment. Only limited investigations are documented in literature. In addition, these investigations differ considerably regarding storage conditions and, therefore, are hard to compare. The fatigue behaviour of a high-strength concrete has been investigated at the Institute for Building Materials Science, Leibniz University Hannover, over the last years regarding different influences. In this paper, results of two research projects are comparatively analysed, focusing on the effect of surrounding water on the numbers of cycles to failure of a high-strength concrete. Thereby, additional influences of loading frequency and size effect are considered. The results clearly demonstrate that the fatigue resistance expressed by the numbers of cycles to failure is reduced by wet environment, meaning storing and testing submerged under water. In addition, indications were found that the moisture content of the high-strength concrete also affects the fatigue behaviour.
