Abstract

Textile reinforcement of concrete structures is promising trend in modern construction. These structures are lightweight, strong, stable, and require fewer materials. However, the use of textile-reinforced concrete in cantilever structures has not been previously studied. The authors designed and manufactured prototypes of lightweight textile-reinforced concrete cantilever coverings. The prototypes underwent strength testing in the laboratory. In addition, finite element modelling was performed to analyze the stress-stain state of the structures. Tre results showed that the maximum failure load of the prototype was 400 N, equivalent to a stress of 4.08 MPa, exceeding the strength of B20 class concrete by 1.9-2.4 times. The effectiveness of textile reinforcement was demonstrated under critical loading conditions, and the residual strength of the structure provided stability after the concrete matrix failure. The prototype could form the basis of commercial solutions. This technology is promising for use in regions with stringent structural reliability requirements, including seismically active zones.
