Abstract
Large diameter monopiles are an established foundation type for offshore wind energy converters (OWEC), although currently practical experience in the design and the behavior of these constructions is rare. Achmus et al. (2008) developed a method for estimating the permanent pile deformation under one-way loading which is to be expected over the lifetime of an OWEC. The procedure, called the stiffness degradation method (SDM), is based on the combination of cyclic drained triaxial test results with numerical simulations. Although it yields plausible results, further validation of the method by comparison with experimental results is very important to ensure its applicability. Recently, LeBlanc et al. (2010) presented the results of a series of 1g-model tests of a monopile in sand under cyclic horizontal loading. These test conditions were modeled with the SDM under drained conditions in order to verify the procedure. The comparison of numerical and test results proves the applicability of the stiffness degradation method.
