In this study, the multiscale synthetic eddy method, which can establish coherent turbulent structures and satisfy predefined turbulent statistical and spectral properties, is employed to generate the inflow turbulence for large-eddy simulation of a high-rise building. The recycling method of Lund and synthetic eddy method is also applied to assess the suitability of multiscale synthetic eddy method. The wind pressure at each mesh face centre on the surface of the high-rise building model is exported in the simulation to determine the wind-induced aerodynamic loads. Compared with the synthetic eddy method, the multiscale synthetic eddy method result is in higher agreement with that of the recycling method of Lund in terms of the wind pressure distribution, wind load characteristic and external flow field of the high-rise building.
