Title:
Abstract:	Für die Bauaufgabe Grünbrücke sind verschiedene Bauwerkskonstruktionen bekannt und in der Vergangenheit ausgeführt worden. Unter den besonderen Bedingungen einer ebenen Topografie und der Errichtung der Bauwerke unter Aufrechterhaltung des Verkehrs über bestehenden Autobahnen mit hoher Verkehrsbelastung wird eine mittelstützenfreie Verbundkonstruktion beschrieben sowie auf die Besonderheiten in Planung und Herstellung eingegangen. Im Land Brandenburg wurden in den letzten drei Jahren drei dieser Grünbrücken gleicher Bauart mit Verbundfertigteilen errichtet. Green bridges as composite structures Several types of structures are known to build green bridges and have been implemented in the past. Under the particular conditions of an even topography - even or flat terrain - and of construction whilst maintaining traffic above existing highly frequented motorways, a composite structure without central supports is described and the particularities of its design and construction are explained. In the State of Brandenburg, in the last three years, three of these green bridges of the same construction type were erected with prefabricated composite elements.
