Introduction. Experimental methods for studying vibrations of buildings and structures (dynamic tests) make it possible to determine an individual set of parameters of dynamic characteristics of natural vibrations inherent in each building and structure. The method of standing waves was chosen to determine dynamic characteristics; it allows to obtain detailed (with the required degree of detail) and, most importantly, reliable data on the technical condition of the building. Materials and methods. Mobile diagnostic unit “Standing Wave Method” (MSW) recorded the micro-seismic vibrations of building constructions. The layout of sensors with a single reference point was chosen. The standing wave method was applied to develop the software package in order to process the micro-seismic vibrations of the building. Vibration coherence spectra were analyzed to identify the natural frequencies of the building. A GIS model was developed to demonstrate the amplitudes and phases of vibrations in the building. Results. Eigenfrequencies, peak amplitudes, and phase characteristics of the building’s wave field were determined. Patterns of distribution of amplitudes and maps of vibration phases were constructed. Areas, accommodating destructive processes in the brickwork of the building’s bearing walls, were identified and the reasons for their occurrence were established. Conclusions. The dynamic characteristics of the building were obtained in reliance upon the results of dynamic tests of the office building. The analysis of the distribution of these parameters allowed to assess the technical condition of the building and to make recommendations towards its strengthening. The author suggests that the mobile diagnostic system, employing the standing wave method, can be used to resolve a wide range of problems.
