Zusammenfassung
This project focuses on the use of textile reinforced concrete (TRC) in the design of a bridge. An interesting project in Vietnam is used as a background for this study. The government of Vietnam has a challenging plan to improve the infrastructure in isolated rural areas. Therefore, the main aim is to develop a bridge model that can be applied at different locations. For it, a suspension bridge has been chosen as possible solution because of its adaptability properties and its characteristics. The deck solution that was developed in this project should be suitable for spans ranging between 40 and 150 m. The solution adopted for the deck is based on combining conventional concrete with TRC. Stay-in-place forms (SIP) made only of textile reinforced concrete, define the deck shape. The main dimensions for each SIP form are 5 m length, 2.40 m width and 0.30 m height with a thickness of only 4 cm. The reinforcement of the SIP elements consists of two layers of carbon textile. Moreover, the forms must be manufactured in a specialized factory and then be transported to the construction site. Then, after erection, the required steel reinforcement is arranged on the SIP at the proper location. Afterwards, casting of concrete takes place allowing the deck to behave as a continuous element. The best feature of this system is the possibility of adapting and implementing it for a wide range of span lengths.
