Resumo: | In this research, the influence of the fibre distribution and orientation on the post-cracking behaviour of steel fibre 14 reinforced self-compacting concrete (SFRSCC) panels was studied. To perform this evaluation, SFRSCC panels 15 were cast from their centre point. For each SFRSCC panel, cylindrical specimens were extracted and notched either 16 parallel or perpendicular to the concrete flow direction, in order to evaluate the influence of fibre dispersion and 17 orientation on the tensile performance. The post-cracking behaviour was assessed by both splitting tensile tests and 18 uniaxial tensile tests. To assess the fibre density and orientation through the panels, an image analysis technique was 19 employed across cut planes on each tested specimen. It is found that the splitting tensile test overestimates the post20 cracking parameters. Specimens with notched plane parallel to the concrete flow direction show considerable higher 21 post-cracking strength than specimens with notched plane perpendicular to the flow direction. |

In this research, the influence of the fibre distribution and orientation on the post-cracking behaviour of steel fibre 14 reinforced self-compacting concrete (SFRSCC) panels was studied. To perform this evaluation, SFRSCC panels 15 were cast from their centre point. For each SFRSCC panel, cylindrical specimens were extracted and notched either 16 parallel or perpendicular to the concrete flow direction, in order to evaluate the influence of fibre dispersion and 17 orientation on the tensile performance. The post-cracking behaviour was assessed by both splitting tensile tests and 18 uniaxial tensile tests. To assess the fibre density and orientation through the panels, an image analysis technique was 19 employed across cut planes on each tested specimen. It is found that the splitting tensile test overestimates the post20 cracking parameters. Specimens with notched plane parallel to the concrete flow direction show considerable higher 21 post-cracking strength than specimens with notched plane perpendicular to the flow direction. |
