Innovative structural applications using SFRC and SCC. Aoude, H., Cook, W. D., & Mitchell, D. In pages 565 - 572, Washington, DC, United states, 2007. Experimental program;Performance enhancements;Reinforced concrete column;Self-consolidating concrete;Structural applications;Structural elements;Tensile resistance;Transverse reinforcement;abstract bibtex The addition of steel fibres can improve many of the properties of traditional Reinforced Concrete (RC), including tensile resistance and fracture toughness. However the current use of steel fibre-reinforced concrete (SFRC) in the construction of structures has been very limited. An experimental program was undertaken in order to investigate the performance enhancements that can be gained from the use of steel-fibre reinforced concrete in structural elements such as RC columns and beams. One of the innovations involved the combination of steel fibres with a highly flowable Self-Consolidating Concrete (SCC) mix. The experimental findings show that the use of SFRC in beams can lead to an increased shear resistance. Furthermore, it was found that the addition of steel-fibre SCC in reinforced concrete columns can lead to improvements in peak load-carrying capacity and post-peak response. The results also demonstrated that the addition of steel fibres can partially substitute for the transverse reinforcement in reinforced concrete columns, thereby improving constructability while achieving significant confinement. Finally it was found that the use of a highly flowable SCC mix can allow for the use of higher volumes of fibres while maintaining an adequate level of workability.
