Paper Title:
Deformation Measurement of Concrete by White Light Digital Image Analysis in Frequency Domain
  Abstract

White light digital image analysis in frequency domain is introduced to study concrete deformation. This method has the characteristics of whole-field, non-contact measurement and the simple measuring system and can obtain displacements by frequency domination correlation arithmetic. Displacements of concrete specimen under axial tension are obtained by white light digital image analysis in frequency domain and then strains and Poisson ratio are calculated. Comparing the experimental results and the theoretical values, the error was little and the effectiveness of this method is certified. The applications of different surface features of concrete are studied.
