Abstract

Abstract: According to ASTMC1018—97 the test was carried out to study the flexural toughness of textile reinforced self-stressing concrete (TRSSC) beam. The load-deflection curves were obtained， which are affected by the different kinds of matrix and the content of Tex in fibrous bundle. The results show that the cracking load of self-stressing concrete beams is improved markedly owing to the textile and increase of Tex. However， with the increase cracking load， the flexural toughness index I₅，I₁₀ and I_○20of TRSSC decreased gradually. Meanwhile， a theoretical model of determining the cracking load was established and a computer analysis was given in this paper. The calculation results are in agreement with the experimental results， which indicates that the theoretical model can evaluate the crack resistance of TRSSC beam.

Key words: self-stressing concrete, textile, beam, flexural toughness, cracking load
