Abstract. The article is devoted to monitoring the technical condition of antenna-mast structures in the process of technical re-equipment of the facility. The analysis of changes in dynamic parameter was performed in the course of technical state control during unloading and loading of antenna equipment on the example of a real object in real time mode. It is shown how the period of natural oscillations changed during the technical re-equipment of the object. The dependence of surges of calculated values of the period of natural vibrations of antenna-mast structures on the work performed at the time of measurements, impulse wind load, traffic and other factors is obtained.
Key words: antenna-mast structures dynamic parameters, oscillations, oscillation period, logarithmic decrement of damping, stressed-strained state. - For citation: Valov A. V., Makarov A.
