An analytical model for determining the interfacial bond shear modulus of steel-fibre-reinforced concrete is presented. The bond shear modulus is a constant that linearly relates the bond shear stress to the fibre slippage at the interface. The analytical model is developed based on the axisymmetric modelling of the pulled-out steel fibre from the surrounding concrete. The model assumes elastic behaviour for both the concrete and the steel fibres. The analytical model evaluates the total displacement of the fibre when pull-out loads are applied at the fibre end. Experimental analyses are used in conjunction with the analytical model to determine the bond shear modulus. The results of the numerical analysis of a few selected experiments are presented. The proposed model is used to evaluate a constant value for the bond shear modulus.
