AbstractDer Einsatz kaltverformter Verglasungen ist in der Fassadenindustrie längst “Stand der Technik“ und stellt besondere Anforderungen an Design und Bemessung der Glas‐ und Rahmenbauteile sowie der elastischen und lastabtragenden Klebefugen von Structural‐Sealant‐Glazing‐Elementen. Je nach Vorgehensweise und geometrischen Randbedingungen werden neben den üblichen Lasten zusätzlich permanente Zwangskräfte und Zwangsverschiebungen in die lastabtragenden Silikonfugen eingeleitet. Dieser Aufsatz soll eine Zusammenfassung technischer und ingenieurmäßiger Regeln und Konstruktionsgrundsätze wiedergeben, welche Design und Bemessung lastabtragender Silikonverklebungen in kaltverformten SSG‐Elementen in angemessener Form und unter Beachtung gültiger Sicherheitskonzepte sowie des angestrebten Lebenszyklus ermöglichen.Design and Verification of Structural Silicone Joints in cold‐bent SSG units. Use of cold‐bent or warped glass units in unitized curtain walling has been getting a state‐of‐the‐art application for the last years. This makes special demands on an appropriate design of glass units and frame members as well as on the elastic bonding joints in Structural Sealant Glazing applications. Depending on the approach of producing and installing these units as well as the geometrical boundary conditions the structural silicone joints are going to be affected by additional permanent load reactions and joint movements next to regular loading. This paper shall summarize technical requirements and engineering rules as well as design aspects enabling appropriate design and calculation of structural silicone joints in cold‐bent SSG units. Reflecting a reliable safety concept and the expected life cycle of these load‐bearing bonding joints is part of the approach.
