In this study, an analytical method to evaluate the shape of concrete crack surfaces by means of 2-dimensional Fourie transform has been developed. Amplitude spectrum, phase spectrum and 3 functions are introduced to elucidate the behavior of both amplitude constituent and phase constituent which are obtained by describing concrete crack surfaces in the frequency domain. The verification of results derived from applying the proposed method to an actual concrete crack surface formed under tensile stress mode has provided not only the most suitable analytical condition to evaluate both precisely and efficiently but also has proven useful in analysing this complicated shape in the frequency domain.
