Load-deformation behaviour of concrete tension ties with weft-knitted textile reinforcement
- Conference Paper
The use of non-corrosive high-strength fibrous materials as textile reinforcement allows the construction of more slender elements when compared to members with conventional steel reinforcing bars. This paper explores the load-deformation behaviour of weft-knitted textile reinforcement embedded in a fine grain concrete. In this experimental study, flat concrete specimens with a thickness of 12-16 mm are loaded in uniaxial tension. The study focuses on the comparison of various knitting patterns, materials and geometric features in the knitted textile. Results show that the post-cracking behaviour can be improved for certain configurations in terms of ultimate strength and deformation capacity. The failure mode is governed by the material of the fibres and their coating. Show more
