Speckle photography is a powerful tool adequate to determine small displacements, in micrometer range. Through this information, other characteristics of structure deformation under loads can be determined as stress and strain distribution. In this paper we present the results obtained by applying speckle photography technique to study the behavior of building model. The displacement whole field was obtained by pointwise method. Also we present the strain distribution obtained by finite element method to compare the results obtained by these techniques.
