Abstract: In recent times, steel fiber reinforced concrete (SFRC) slab-on-pile systems without traditional reinforcement has seen increasing popularity owing to its ease-in-construction. In this thesis, a comprehensive experimental and analytical investigation on the structural behavior of SFRC flexural members without traditional reinforcement is presented, with a focus on flat slab systems. First, a constitutive stress-strain relation for SFRC in tension is proposed to study the behavior of SFRC beams at large displacements. Using the proposed constitutive law, the phenomenon of moment redistribution in continuous SFRC slabs without traditional reinforcement is investigated. Subsequently, methods to determine the load-carrying capacity of SFRC flat slab panels without traditional reinforcement were proposed. A semi-analytical model is then presented to determine the load-carrying capacity of internal panels considering the influence of arching action. Lastly, an experimental and analytical study on the behavior of SFRC slabs with and without traditional reinforcement under punching load was carried out.
