The invention discloses a wind vibration realizing method for a double coupled system with consideration a high-frequency base force balance test. With a second-order blind identification technology based on a complex mode theory, decoupling of a coupled measurement signal is realized; and reliable parameter recognition is carried out on a separated signal by using a Bayesian spectral density method based on all-aerodynamic force simulation, so that a separation/mixing matrix, an inherent frequency and a damping ratio of a BMS and thus correction of a distorted aerodynamic signal is realized.On the basis of power calibration, a wind effect and equivalent static wind load calculation method considering the influence of a three-dimensional coupling effect of a super high-rise building structure is established by using a harmonic excitation method, so that defects of the HFFB are overcome to a certain extent and the result becomes real and accurate.
