The demands of applying steel fibres in concrete has increased gradually as an alternative engineering material nowadays. This research embarks on the steel fibre application in self-compacting steel fibre reinforced (SCFRC) concrete ribbed slab structure. In this research, there were two models developed in the Abaqus software, i.e. a ribbed slab model and a solid concrete slab in order to analyze the flexural behaviour of these simply supported structures. The slab models’ overall dimension is 1200 mm width, 2800 mm in length and overall thickness of 200 mm. Based on the experimental work, the concrete slab was designed as Grade 30 self-compacting concrete with 1% steel fibre inclusion. Based on the results, the solid SCFRC slab showed better post-peak behaviour as compared to the SCFRC ribbed slab model. However, the ribbed slab model showed higher maximum stress than the SCFRC solid slab. Therefore, it can be concluded that the SCFRC ribbed slab caters for better stresses in comparison to the SCFRC solid slab. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
