Seven full-scale column specimens, constructed without cover and containing various amountsof fibres and transverse reinforcement, were tested in compression to examine the influence of steelfibres on core confinement. The results demonstrate that the addition of fibres leads to improvements inload carrying capacity and post-peak response, indicating that fibres improve core confinement incolumns. In addition, the influence of fibres in improving the cover contribution was isolated using theresults from experiments on sections containing identical reinforcing cages but with concrete cover. Theresults show that the addition of steel fibres greatly enhances the cover contribution to the overall axialload performance.
