title = "Kinematic-based approach for complete shear behaviour of deep FRC beams",
abstract = "While tests of deep fibre-reinforced concrete (FRC) beams have shown that steel fibres enhance the crack control and shear strength, the modelling of these effects in a simple and rational manner remains a challenging problem. Because FRC features enhanced tension behaviour, it is not well suited for the traditional strut-and-tie approach which neglects the tension in the concrete. Therefore, this paper proposes an alternative approach which focuses on the displacements in the critical shear cracks. The displacements are described with a kinematic model with two degrees of freedom, and are used with appropriate constitutive relationships to estimate the shear contribution of the fibres. This kinematics-based approach is validated with experimental data, and it is shown to capture adequately the complete pre- and post-peak behaviour of deep FRC beams.",
