Effect of Materials Characteristics on Average Crack Spacing of Reinforced Concrete Specimen
Based on three-dimension numerical models, considering the heterogeneities on mesoscopic scale, a set of numerical tests were undertaken using a Parallel numerical test program. The paper investigates the influence of concrete and reinforcement characteristic on failure mode and stress distribution of the reinforced concrete specimens under uniaxial tensile stress. It can be found, the concrete strength is considered an important factor to significantly influence the average crack spacing, tension stiffening phenomenon exists during the failure process of the specimen, the average fracture spacing is increased and the initial peak load is also increased with the increasing of the strength value of the concrete. Accordingly, the average fracture spacing and the initial peak load is also increased with the increasing of the concrete strength value. It can be concluded that the mechanical capacities of the concrete has more effect on the failure mode and initial peak load, but has little influence on the ultimate load capacities of the specimen.
