The method of localization of changes in the deflected mode is based on the analysis of time series of oscillations (displacement, velocity, acceleration) of building constructions and structures. The method is based on the hypothesis that any changes in the deflected mode of structures result in changes in the oscillation energy. In this case, once the information on the structure oscillation parameters in different points of the building is available, the changes in the oscillation energy will signify the changes in the deflected mode in the relevant points.
