Abstract [en]

The present assembling detail between two segments of the tubular tower segments used in to support wind turbines is accomplished by flange connection. This type of connection suffers from a rather low fatigue resistance class, in the range of 40 MPa. To remedy this drawback a new friction joint has been developed in the recently finished international RFCS research project HISTWIN (High-Strength Steel Tower for Wind Turbine). In order to study the behaviour of both type of joints, conventional ring-flange connections and friction connection, eight "Four point bending tests" of down-scaled tubular tower section were performed. The behaviour of tests using the friction connection is described in this paper. A short summary of the experimental and numerical work, performed at RWTH and LTU, respectively, is presented in this paper.
