The 3-dimensional shape of a concrete crack surface results from the crack-forming process under a certain stress condition, and the properties of the shape provide important data for elucidation of formation and extension mechanisms. We previously presented analysis functions to represent the shape properties of a concrete crack surface based on the 3-dimensional coordinates obtained by a measurement system using the structured light projection method. Fourier analysis are widely used methods for analyzing shapes of objects, but these methods have not been applied to analysis of concrete. It is certain, however, that Fourier analysis can be useful to determination of the shape of concrete crack surface. As the first step to achieving our final goal of the establishment of accurate constituve law of concrete , we show here the usefulness of Fourier transform as a method for determining the shape properties of a concrete crack surface.
