Abstract:	Gelenkkonstruktionen aus Beton werden seit gut 100 Jahren erfolgreich im Hoch- und Brückenbau eingesetzt. Die von Augustin Mesnager entwickelten Federgelenke zählen dabei zu den unvollkommenen Betongelenken. Diese Gelenke sind wartungsfrei, wirtschaftlich und besitzen gegenüber unbewehrten Betongelenken nach Eugène Freyssinet aufgrund der gekreuzten Bewehrungsstähle eine erhöhte Beanspruchbarkeit gegenüber Querkräften. Der Beitrag gibt einen Überblick über die Entwicklung der Gelenkform von der ersten Idee Mesnagers bis zur erfolgreichen Anwendung im Hoch- und Brückenbau. Es werden die durchgeführten experimentellen Untersuchungen zum Trag- und Verformungsverhalten der Federgelenke vorgestellt. Die wesentlichen Erkenntnisse werden zusammengefasst und Empfehlungen für die Bemessung und Konstruktion von Betongelenken bei großen Querkrafteinwirkungen abgeleitet. Use of semi-articulations in structural and brigde engineering. Concrete hinges have successfully been used in civil engineering constructions since over 100 years. Semi-articulations invented by Augustin Mesnager are classified as incomplete concrete hinges. These hinges are maintenance-free, economically and because of the crossed reinforcing bars in the hinge throat they are able to carry higher shear forces than unreinforced concrete hinges after Eugène Freyssinet. This paper gives an overview of the historical development of this type of hinge from the first idea of Mesnager till the successful use in civil engineering structures and bridges. The known experimental investigations of the bearing and deformation behavior are presented. The main findings are summarized and recommendations for the design and construction of concrete hinges under high shear forces are given.
