Abstract

The research studies presented focus on the influence of shear key geometries to the fatigue design of axially loaded hybrid connections in offshore wind energy converters. Within a national research project fatigue tests of grouted joints were carried out and used for the benchmark of numerical models. With the results of stress calculations from the numerical model, different local concepts for the fatigue design of steel members were implemented and evaluated. The calculation showed non-linear relations between geometric dimensions and stress concentrations. It became obvious that for future investigations linear elastic approach has to be extended taking fracture mechanic for steel and grout material into account.
