Study on interference effects of wind induced response of a tall building

Abstract:Based on the wind tunnel test of a tall building, wind induced response was analyzed in detail in different conditions, and the interference effects were  also discussed. The results show that the interference effect of the base moment is mainly shielding effects. The base moment will be decreased when the building is shielded, but the base moment may be increased when the disturbance are located on the side wind or down wind. When disturbed, the change of background components is similar to the mean components, but the change of resonant components is irregular. Also the change of the peak acceleration is irregular when disturbed.
Keywords:tall building; wind induced response; interference effects; wind tunnel test
