Abstract

When mixed to concrete, discrete steel fibres "work" as a smeared reinforcement, being able to bridge flexural and/or shear cracks. So, steel fibres may replace part of the usual reinforcement bars, allowing to eventually decrease costs. In this work, the results of an experimental investigation regarding punching behaviour of normal strength Steel Fibre Reinforced Concrete (SFRC) flat slabs is presented. Six specimens were tested using different fibre volume contents (0, 0.5%, 0.75%, 1 % and 1.25%) along with the experimental testing regarding the determination of the mechanical properties of SFRC, namely, its compressive and tensile strength, along with tensile behaviour thru an inverse analysis of flexural tests results. Results showed that both, an increase of the slab load capacity, and of its deformation, when compared with the reference slab, where SFRC was not used. Finally, the results were compared with different design proposals.
