On an example of a complex engineering structure with aerodynamically unfavorable constructive form, equipped with mechanisms dampers, the results of long-term observations of the oscillation frequency under the influence of wind loads were reviewed. The experimental dependence of the first tone oscillation frequency on time for this structure is shown. The hypothesis on the causes of frequency oscillations change in engineering structures in time is proposed. The experimental data confirms this hypothesis. The results of a comparison of the experimental data for long-term observations with the oscillation frequency in accordance with the safety criteria of GOST 31937-2011 “Buildings and Constructions. Rules of inspection and monitoring of the technical condition” are shown. It has been shown that the results of comparison indicate technical safety of the whole object. It is offered to use dynamic monitoring systems for technically complex heavy-duty engineering structures for early detection of the transition beginning of the control object to the limited functional or emergency condition.
