An algorithm for the experimental determination of the defective zones of the construction with free support is presented. A reinforced concrete floor plate freely supported on both sides is studied as an example. The oscillation method is used as a diagnostic method. Impact loading is used as the excitation of non-stationary oscillations. The studies were carried out using an oscillation measuring setup. The research is based on the analysis of oscillation modes under non-stationary dynamic loading of an object. The analysis of oscillation modes makes it possible to detect the conditionally defective zones of floor plate.
