Abstract: Ductility is an important factor in the design of reinforced concrete (RC) structural elements. Recently, several researchers have demonstrated that steel fibres can improve the response of traditional reinforced concrete. One possible application for the use of steel fibres is in reinforced concrete columns, however the addition of steel fibres in traditional concrete mixes can cause problems with workability. The use of self-consolidating concrete (SCC) can potentially improve workability and facilitate placement. An experimental program was undertaken at McGill University to examine the feasibility of partial replacement of transverse confinement reinforcement in RC columns by using SCC containing steel fibres.
Several full-scale RC columns, with various ratios of confinement reinforcement and with various fibre contents, were tested under pure axial loading. The results demonstrated that this approach can lead to significant improvement in performance while also improving the constructability of ductile columns.
