Abstract
This paper sum marises static and dynamic axial compression tests on small scale grouted joints for offshore wind energy converters. The connection is mostly used between driven monopiles and tower sections as tube-in-tube connection. The gap between the tubes is filled with grout materials. The test series comprises grouted joints with smooth and ribbed surfaces of the tubes which are loaded by axial compression. The ultimate and fatigue limit state of the connection can be increased with shear keys along the overlapped length of the tubes to get a ribbed contact surface to the grout. In this case the axial load is transferred by compression struts between the shear keys. The bearing capacity depends mainly on the compressive strength of the grout and the geometry of the shear keys. In addition to the experimental results an analytical design concept is presented within this paper for grouted joints with shear keys. With the analytical model the axial load capacity of the grouted joint can be determined under consideration of the compression struts and number of shear keys.
