Correlation of pressures on a surface is a characteristic determinant of the aeroelastic loading of a civil engineering structure like tall building. Measurements of wind load on a model of an existing building has been conducted and boundary layer wind tunnel has been utilized in order to obtain variable pressures at the points of the building model under various wind attack angle. The effects of the air flow fluctuations were measured, as a rule by the pair of sensitive microphones. Pressure time series has been subjected to an correlation and spectral analysis results are presented in the article. Assumption of the homogeneous turbulency field has been shown to be rather conservative when dealing with wind resistant dynamic design of the structure.
