Abstract

Abstract

Based on the investigation on the flexural toughness according to DBV,it was analysed the steel fiber distribution in the cross-section of testing beams.The results indicated that steel fiber distribution in the failure section could have a high scatter for different beams with the same fiber content;the relationship between the fiber content and fiber number per unit cross-sectional area was established by the linear regression of the statistical data,which could predict the fiber number at the damaged section in case of different fiber content.The test results showed that the toughness of the beam could be significantly affected by the fiber distribution in the cross section.
- flexural toughness,
- fiber distribution,
- fiber number,
- fiber distance
