One of the most important issues in engineering design is to investigate the occurrence of cracks and how they extend. This causes structural, reliability and durability problems in structures, structural safety evaluation, analysis of attenuating cracks, hypothetical models for concrete behavior. In pressure, tensile and shear. Investigating the behavior of RC members requires study of crack propagation and its effect on strain stress relationship in cracked environment. Reinforced reinforcement, crack propagation mechanism in reinforced area, microtubule development against single cracks in reinforced concrete area. Given that an appropriate behavioral model is developed from the selection of appropriate behavioral models based on the concepts of linear failure, the modeling of the multipurpose RC models and the results are compared with the experimental results. In this paper special attention is paid to the methods of repair and maintenance of concrete cracks.
