| Abstrakt: |
The application of high-strength structural bolting assemblies of the HV system according to EN 14399-4 and EN 14399-6 and DASt-Richtlinie 021 with large diameters up to M72 as preloaded bolting assemblies in highly loaded steel structures like offshore wind towers, where the connections are exposed to low temperatures beside static and fatigue loads. To close the lack of knowledge on low temperature behaviour of these bolts, systematic investigations were carried out to determine the tendency of brittle fracture of high-strength bolts with large diameters. This paper presents the main results of the experimental investigations on the tendency of brittle fracture in terms of component tests at low temperatures. |
