Abstract :
[en] This paper investigates the influence of turbulence intensity in the oncoming flow on the admittance function of local pressures on a building roof. Using Large-Eddy Simulations (LES), the study analyzes the power spectral densities of wind pressure at selected points on the roof of a model building and their relationship to wind turbulence. The results show that while the overall pressure distribution scales with the turbulence intensity of the oncoming flow, and that the pressure spectra on the roof, near the leading edge, although being affected by level of turbulence, yield very similar admittance functions in the bubble near the leading edge.
