Title:
Abstract:	Im baden-württembergischen Albstadt wurde eine ältere Fußgängerbrücke aus Stahlbeton durch eine elegante Brücke aus Textilbeton ersetzt. Durch die Kombination von textilbewehrtem Beton mit einer Vorspannung ohne Verbund ließ sich eine für Betontragwerke außergewöhnliche Schlankheit erzielen. Die 97 m lange Brücke über die Bundesstraße B 463 besteht aus sechs Fertigteilen, die bei einer Elementlänge von 17,2 m eine Bauhöhe von nur 43 cm aufweisen. Im Beitrag werden Konstruktion, Bemessung und insbesondere das Schwingungsverhalten beschrieben. Des Weiteren wird über die Erfahrungen aus mehr als vier Betriebsjahren berichtet. The worldwide longest textile-reinforced concrete pedestrian bridge - Technical details and practical experiences In Albstadt, Germany, the former pedestrian bridge, which was made of steel-reinforced concrete, had to be replaced by a new construction made of textile-reinforced concrete. Due to the combination of textile-reinforcements and an unbonded prestressing a remarkable slenderness of the superstructure was achieved. The 97 m long bridge over the state road B 463 is built up of six prefabricated concrete elements, which have a maximum element length of 17.2 m while the construction height is only 43 cm. The article deals with details of the construction, the structural analysis and the dynamic behavour in particular. Furthermore, experiences after a lifetime of four years are reported.
