Being a part of structural aerodynamics as a recognizable disciplin\u011B of engineering applications is a consequence of a practical demand for the more complex and safe design of speci\u00E1l wind sensitive structures like bridges, footbridges, masts and towers. Stochastic processes acting in combination with extr\u00E9me static and dynamic impacts and creating repeated instable and non-linear response characterize their load. lis origin and demonstration can be explained on the basis of a combination of the theoretical and experimental research only. Such a research is the essence of Ihe proposal that is focused on the further development of the gener\u00E1l methodology of aeroelastic stability of non-aerodynamic profiles including additive and parametric noises.
