This paper presents the results of an experimental and analytical study that was carried out to improve the understanding of the response of cracked concrete from a fracture mechanics point of view. Reinforced concrete panels made of normal- and high-strength concrete were tested under uniaxial tension. A previously proposed fracture energy model was modified to predict the obtained tensile response of both normal-and high-strength concrete panels. Steady crack growth was described with energy equilibrium during cracking. A new method is proposed to approximate the effective compliance for a member with multiple cracks. For a given cracking stage, the model can predict concrete and steel strains and entire load-deformation curves. The proposed fracture energy model is also capable of predicting the minimum reinforcement ratio of normal- and high-strength concrete tensile members of different sizes.
