Control and assessment of the technical condition of the construction of the spatial construction of the International Exhibition Center (Kyiv, Ukraine) according to its dynamic characteristics. The subject of the study is the frequency and form of natural oscillations of the shells without and with consideration of the load; amplitudes of steady forced nonlinear oscillations; critical values of loads, deformations and equivalent stresses. Stress-deformed state, frequencies and forms of self-oscillations of load-bearing structures of a spatial building structure. The practical significance of the obtained results lies in the application of the numerical method of determining the stability of steady forced nonlinear oscillations of thin shells to the solution of the actual scientific and technical problem of construction mechanics to ensure their trouble-free operation at the stage of designing spatial structures.
