A study was conducted to analyse the fracture behavior of reinforced con- crete tensile members. The main objective was to improve the current understanding of the response of cracked high strength concrete elements based on fracture mechanics considerations. The average contribution of concrete in reinforced elements was experimentally analysed from forced panels subjected to uniaxial tension. The predictivness of a previ- ously proposed fracture energy approach based on non-linear fracture mechanics was examined. A new method is derived to approximate effective compliance for normal and high strength concrete members with multiple cracks. In addition, a simplified R-curve method is proposed to approximate the fracture behavior of cementitious materials with a nounced brittle fracture response.
