Compared with the conventional damage feature indices generated from vibration testing this novel damage feature index is of some advantages and distinguishing features. It is found that there exists a good linear correlation between the fractal dimension and the natural frequency, which shows that the fractal dimension of surface-crack distribution is able to act as a damage feature index to reflect the damage degree of concrete structures effectively.

Then fractal geometry is employed to investigate the crack evolving process of concrete structures and the relationships between the fractal dimension of surface-crack distribution and the mechanical properties of the damaged structures are discussed in detail. This shows that fractal dimension is able to characterize the surface-crack distribution quantitatively. It is revealed that the surface-crack distribution of the damaged concrete structures takes on fractal behavior. The fractal characterization in the evolving damages of concrete structures is studied based on physical model experiments.
