After cracking has occurred, steel fibres in concrete allow tensile stresses to be transferred across the crack edges and ensure a mechanically usable tensile strength. The thesis investigates the punching shear behaviour of steel fibre reinforced flat slabs with and without punching shear reinforcement and practice relevant slab thicknesses. Based on 16 experiments, a comprehensive literature research and theoretical considerations, an existing, mechanically based design model is developed further with regard to the consideration of the fibre contribution.
