Light-weight precast shell elements made of textile reinforced concrete: production, experimental investigations and application potential

For single curved barrel-vault shells made of textile reinforced concrete (TRC) a manufacturing process has been developed that comprises the production of the precast parts as well as tailored solutions for transport and mounting of the filigree shells at the construction site. Furthermore, the load-bearing capacity of the shells could be verified experimentally using large-scale tests of prototypes. Saw cuts document the high production quality of the precast parts. The developed methods were successfully applied within the research project by constructing a large-scale roof structure consisting of five barrel-vault shells. The cross-sectional thickness of the 10 m² large elements amounts to only 2 cm emphasizing the high strength and application potential of TRC.
