“…For reinforced concrete members subjected to uniaxial tension, the structural load-displacement curves obtained by the numerical tests for the different concrete strength value are compared in Fig. 3 (The comparison between the model behavior of plain concrete prism and the reinforced concrete prism had been done in reference [7]). Initially, the load-displacement curve represents the elastic behavior of the member up to the initiation of the first crack.…”

“…It is well known that the periodically distributed fracture spacing phenomenon exists in the failure process of the reinforced concrete prism under uniaxial tension. For the crack spacing, it depends on bond transfer condition, the size of bond transferring zone, the ratio of elastic modulus of the reinforcement to concrete; of course, the concrete is also an important factor influencing the mean crack spacing and the crack distribution [3][4][5][6][7]. Three reinforced concrete prism specimens with different concrete strength under uniaxial tension are used for the present study.…”

The goal of the present work is to investigate the influence of concrete on failure mode and stress distribution of the reinforced concrete specimens under axial tension by using a numerical test code named Realistic Failure Process Analysis. It can be found that, the periodically distributed fracture spacing phenomenon and tension stiffening phenomenon exist in the failure process of the reinforced concrete structure. Besides, the effect of concrete characteristics on the mechanical behavior and crack spacing of reinforced concrete was also studied in three samples with different concrete strength. The concrete strength value is considered to be an important factor not only to significantly influence the average crack spacing but also to influence the initial peak load of the specimen. In addition, the average fracture spacing is increased and the initial peak load is also increase with the increasing of the concrete strength value, but the mechanical capacities of the concrete has little influence on the ultimate load capacities of the specimen.

“…For the crack spacing, it depends on concrete strength, bond transfer condition and the size of bond transferring zone. It is proved that the ratio of elastic modulus of the reinforcement to concrete is also an important factor influencing the mean crack spacing and the crack distribution [2][3][4][5][6][7][8][9]. The fracture spacing phenomenon of reinforced concrete structure involved in materials science, Engineering science and many other research fields, it was mechanics phenomenon and science problem.…”

A numerical test code named RFPA (Realistic Failure Process Analysis) was used to investigate the stress filed transformation process of the reinforced concrete specimen under uniaxial tensile loading. The periodically distributed fracture spacing phenomenon exists in the reinforced concrete structure and the concrete cover thickness was an important factor influence the average crack spacing and crack number. The numerical simulation results show that the stress fields on the concrete between the two adjacent cracks go through a variation process from tensile stress to compressive stress with the increasing of the concrete cover thickness value. It is clear that the stress distribution and fracture spacing were related to the concrete cover thickness under the condition that the materials characteristics were certain (such as concrete and reinforcement materials).In addition, if there was a new crack produced, the location was sure in the middle of the two adjacent cracks since the maximum stress occurred in the middle of the two adjacent cracks. So, it indicates that the concrete cover thickness can influence the average fracture spacing and the crack number in the reinforced concrete prism specimen.
