(3) Compared to traditional methods, current method avoids discontinuity problem of thefluctuating wind of the vehicle and shows higher simulation efficiency. Therefore, theproposed method could facilitate the analysis of aerodynamic response of thevehicle-bridge coupled system.However, the proposed method has only been validated by the analytical fluctuating windspectrum. As the field test is both time-consuming and cost expensive, and the dynamic dataobtained from the wind tunnel test is not sufficient enough in length, Computational FluidDynamics(CFD) method will be adopted in the future work to validate the proposed method.
