Abstract:
Textile-reinforced concrete (TRC) is a composite material consisting of textile reinforcement and fine-grained concrete. Because of different bond performance and material properties of textiles compared to reinforcing steel, the load-bearing behavior of TRC differs from that of ordinary reinforced concrete. As a consequence, the design methods for ordinary reinforced concrete cannot be directly applied to TRC structures. This paper investigates the load-bearing behavior of TRC. Design methods for TRC are derived considering different textile properties and different loading conditions such as tension, bending, and shear. Based on the extensive theoretical and experimental investigations conducted, design methods have been derived that allow the dimensioning of TRC structures. Further investigations are aimed at identifying appropriate applications for TRC. The results of theoretical and experimental investigations conducted have been put into practice by producing TRC elements for applications such as façade elements, formworks, and tanks.
