By using the harmony superposition method (HSM), the wind velocity time history was simulated and converted to wind load time series. Applying the wind load time series to funnel-shaped open membrane structure(FOMS), the structural wind-induced vibration response and the wind-induced dynamic magnification factor were numerically investigated. The results revealed that the wind-induced nodal displacement, the velocity and acceleration responses of FOMS were stable, and the statistics for the wind-induced nodal displacement time history followed the Gaussian distribution. Furthermore, the windinduced dynamic magnification factor related to different parts of the structure varied significantly and the windinduced dynamic magnification factor on the windward part of structural system was greater than that on the leeward part.
