For the purpose of investigating the frequency characteristics of the shape of concrete crack surfaces, 25 concrete crack surfaces which were formed under 4 kinds of stress modes in normal strength concrete have been analyzed using 2-dimensional Fourier transform. An analytical method proposed in the previous paper has been applied to evaluate the behavior of amplitude constituent and phase constituent obtained by describing concrete crack surfaces in the frequency domain. The results show the resemblances among the frequency characteristics obtained from all of the crack surfaces that are not affected by the difference of stress modes. And the fact seems to show the possibility of generating standard shape model for concrete crack surfaces.
