Abstract
Design of steel fibre reinforced concrete with and without additional rebars. Design of steel fibre reinforced concrete with and without additional reinforcement is defined in Germany by the approved guideline ”Steel Fibre Reinforced Concrete“ of the German Committee for Reinforced Concrete (DAfStb). According to the guideline, the crack-bridging effect of steel fibres is determined on an experimental basis via standardized four-point bending tests, idealised as residual flexural strength and quantified or classified in terms of performance classes. For concrete design in ultimate and serviceability limit state, stress-strain curves of the steel fibre reinforced concrete in tension apply which additively add the steel fibres effect to the well-known resistance equations for reinforced concrete. The paper illustrates how to derive design values of residual tensile strengths on the basis of residual flexural strengths and the associated stress-strain relations. Based on this, design equations in ultimate and serviceability limit state are described. Overall, a compact overview on the mechanical principles and design approaches of steel fibre reinforced concrete is given.
