Title: Load-Bearing Behavior of a Pedestrian Bridge Made of Textile Reinforced Concrete

Abstract:A pedestrian bridge in Albstadt, Germany showed immense corrosion damages of the steel reinforcement. The damages were so immense that the bridge had to be torn down due to a lack of load-bearing capacity and, therefore, replaced by a new bridge. The architectural design follows a slender construction principle, thus, by using the new composite material textile reinforced concrete (TRC) a slender concrete superstructure is achieved. By using non-corrosive textiles, concrete covers can be reduced to a minimum of only some millimetres and cross-sections are minimized. The paper describes the design, structural analysis, load-bearing behavior and production processes of a 97 m (3819 in.) long TRC pedestrian bridge. The whole construction is subdivided into six prefabricated parts, each offering a maximum length of L=17.20 m (677 in.) and a maximum span of Ls=15.05 m (593 in.). The cross-section, which is a T-beam, has a height of only H=0.435 m (17 in.) resulting in a slender bridge construction with a slenderness ratio of H:Ls = 1:35.
