The paper analyzes the problem of detection and identification of the defects in the layers of the buildings. In order to analyze the behaviour of the damaged and un-damaged layer, the defects in the layers were modelled using physical and Finite Element models. The modal analysis of building's laboratory model prototype layer was performed and the results in the field of time-frequency were analyzed. Fourier analysis of the changes in layer dynamics with various defects showed that the method can be used for layer defect diagnostics. The results also allowed determining power spectral density, which correlates with the changes in layer condition.
