This project deals with behaviour and capacity of steel fibre reinforced concrete (SFRC) flat slabs under punching shear force. A total of twelve small-scale flat slabs of different dimensions that consisted of nine SFRC were tested. Effect of steel fibres amount on punching shear behaviour and resistance of the slabs was investigated. The results show a significant increase of the punching shear capacity and considerable improvement of cracking behaviour as well as good integrity of column-slab connection of the slabs with fibres. The slabs without fibres failed suddenly in a very brittle manner, while the fibre-reinforced ones collapsed in a more ductile type. As the size of the specimen is increasing the shear strength of the specimen decreases. Here the percentage of steel fibre is increased but the punching shear strength of the slab is decreased.
