The paper considers an approach to assessing the dynamic parameters of column-type building structures under passive seismoacoustic monitoring. To describe the response of the object, a mathematical model in the form of a superposition of damped oscillators is proposed, and its parameters are determined by minimizing the agreement criterion between the model and the experimental data. Spectral analysis, the Levenberg–Marquardt method, and Monte Carlo trials are used to obtain the optimal solution. It is shown that the free parameters of the model, in particular the damping characteristics, are informative for identifying the technical state of the object and can be used for long-term monitoring. The results indicate that, at the time of observation, the object was in a stable stationary state.
