A significant amount of research has been carried out on the material and structural characteristics of fibre reinforced concrete (FRC). Chapter 1 presents a literature survey of the historical background and development of FRC. New experimental data on the direct tensile, cylinder splitting, flexural, and cube crushing strengths of both plain and fibrous concretes is provided in Chapter 2. An analytical formula for predicting the direct tensile strength of FRC has also been derived. Chapter 3 comprises two tension softening models (i.e. TSM and EMIS models) for simulating the complete pre-cracking and post-cracking responses of cementitious composite. Both models have been validated using various experimental data. Chapter 4 addresses the characterization of the fiber-matrix properties where fibre pull out tests have been conducted for various types of deformed fibres. Chapter 5 covers the nonlinear finite element modelling of the deformed fibre pull out from cementitious matrix. A fibre pullout model has been developed and validated using experimental results. Chapter 6 concentrates on the simulation of the complete loaddeflection response and failure pattern of FRC flat slab at slab-column connection. Parametric studies on the slab thickness and reinforcement ratio have been conducted. Simulations of FRC flat slab and beam structures have also been performed using the EMIS model. Chapter 7 cites the details of a general analytical model for the prediction of ultimate punching shear strength of flat slab at slab-column connection. The analytical model is shown to provide reasonably good improvement when compared to several major design codes. Additionally, a unique analytical expression that provides useful information on the failure mode of flat slab has also been derived. Finally, Chapter 8 summarizes and concludes the outcomes and achievements throughout the research and possible areas for further research are suggested.
