Abstract: In this paper, a series of studies to reinforced concrete cracks have been done by image graying, calibrating, image denoising, image enhancement and image segmentation, and the binary image of cracks is finally obtained. Using the Box Method, the fractal dimension of cracks is determined. The relationships between the fractal dimension of surface cracks in the cracking beam under three-point loading and some other factors, such as the acting load and the deflection of the beam span, are studied respectively. The results show that the fractal theory is feasible to describe the concrete cracks development. Furthermore, it shows that the crack information in reinforced concrete structure obtained by the fractal theory will lay the foundation for the assessment of service state of concrete structure.
