Abstract:

The pedestrian bridge over a state road in Albstadt, Germany, had to be torn down due to immense corrosion damages of the steel reinforcement. The design of the new bridge allows a slender construction, thus, the new composite material textile reinforced concrete (TRC) is used. By using textiles made of non-corrosive materials like alkali-resistant glass rovings, concrete covers can be reduced to a minimum of only some millimetres to minimize the cross-sections.

The paper describes the design, structural analysis and load-bearing behavior of a 100 m long pedestrian bridge subdivided into six prefabricated TRC parts, each offering a maximum length of

17.20 m and a maximum span of 15.05 m. The 3.21 m wide cross-section, which is a T-beam, has a height of only 43.5 cm resulting in a slender bridge construction with a slenderness ratio of only H:L = 1:35.
