Title:
Abstract:	In Albstadt-Lautlingen 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 43 cm aufweisen. Im Beitrag werden Konstruktion, Bemessung und insbesondere das Schwingungsverhalten beschrieben. Die Untersuchungen zu den verwendeten Baustoffen sowie zum Tragverhalten und zur Dauerhaftigkeit finden sich in einem separaten Beitrag in diesem Heft. A Pedestrian Bridge Made of Textile Reinforced Concrete The pedestrian bridge over a state road in Albstadt, Germany, had to be torn down due to immense corrosion damages of the steel reinforcement and was replaced by a new bridge. The design of the new bridge allows a slender and durable construction with high demands on the concrete surface. The bridge with a total length of 97 m is subdivided in six prefabricated parts with a maximum element length of 17,2 m and a span of Ls = 15 m. The height of only 43 cm is possible by using the innovative composite material textile reinforced concrete. Thus, a slenderness of Ls/H = 35 and an extreme slender bridge construction is achieved. Due to the non-corrosive textile reinforcement a very small concrete cover is possible and, thus, webs and cantilever arms can be designed very thin. The paper describes the construction, design and dynamic behaviour. A report on materials, load bearing behaviour and on the durability is available as a separate paper in this issue.
