Despite the wide research and the continuously increasing structural applications of fibre reinforced concrete (FRC), the use is still restricted with respect to its potentials. This is mainly caused by the lack of international building codes for FRC structural elements and the incomplete understanding of its complex behaviour. This paper therefore presents the results of an experimental and analytical investigation on the shear capacity of 6 prestressed steel fibre reinforced concrete beams. The beams are subjected to a four-point bending test until failure and the main investigated parameters are the fibre dosage, the amount of prestressing and the amount of shear reinforcement. Both traditional mechanical measurement devices as advanced optical techniques are used.
