Title:
Abstract:	Das Tragverhalten und die Bemessung von Grout-Verbindungen von Offshore-Windenergieanlagen ist Gegenstand gegenwärtiger Forschungsvorhaben, wie beispielsweise dem Projekt GROWup, und noch nicht hinreichend geregelt. Derzeit existieren mehrere Regelwerke und Leitfäden, welche in Folge von berichteten Schäden an Grout-Verbindungen aus dem Jahre 2009 überarbeitet werden. Dieser Artikel behandelt im Wesentlichen Inhalte der Technical Note for the Certification of Grouted Connections for Offshore Wind Turbines [1]. Die Technical Note (TN) fasst den aktuellen Stand der Forschung zusammen und gibt neue Bemessungskonzepte an, die eine sichere und ökonomische Bemessung der Grout-Verbindung gewährleisten sollen. Sie soll als erster Schritt in Richtung einer angestrebten Normenharmonisierung dienen, um eine einheitliche, wissenschaftlich abgesicherte Bemessung von Grout-Verbindungen im Offshore Windsektor zu erreichen. New approaches for the verification of cylindrical grouted connections of offshore wind energy turbines. The bearing behavior and the assessment of grouted connections of offshore wind turbines is subject of research (e. g. the GROWup project) and not uniformly regulated in existing rules and standards. As a consequence of sliding damages at a number of offshore wind farms reported in 2009 existing rules and standards have been reviewed. This article basically deals with the content of the Technical Note for the Certification of Grouted Connections for Offshore Wind Turbines [1]. The technical note (TN) describes the current state-of-the-art for the application of grouted connections under consideration of the latest state of research. Also new approaches were introduced to ensure a safe and economic assessment. The aim is to reach a harmonized standard for the design of grouted connections.
