Based on the simultaneous pressure measurements of the rigid model of Wuhan Tianhe International Airport Phase III (expansion of ATC tower) Project in a wind tunnel test, the characteristics of the wind loads on the oval-shaped high-rise structure were investigated. This paper discussed the distributions of mean and peak wind pressure coefficients on numerous test points under typical wind directions. Based on the time-histories of wind loads and FFT method, the spectra of 3-D wind loads on the oval-shaped structure were obtained for 90° approaching wind direction (corresponding to the maximum windward area). The power spectra were then fitted by using the empirical formula. The mean, background and resonant equivalent static wind loads were determined by the LRC wind load method. The results were compared with those by the inertia wind loading method. It is found that the equivalent static wind loads by these two methods are in good agreement.
