Experimental study on wind-induced dynamic interference effects between two tall buildings
Peng Huang and Ming Gu

 
Abstract
    Two identical tall building models with square cross-sections are experimentally studied in a wind tunnel with high-frequency-force-balance (HFFB) technique to investigate the interference effects on wind loads and dynamic responses of the interfered building. Another wind tunnel test, in which the interfered model is an aeroelastic one, is also carried out to further study the interference effects. The results from the two kinds of tests are compared with each other. Then the influences of turbulence in oncoming wind on dynamic interference factors are analyzed. At last the artificial neural networks method is used to deal with the experimental data and the along-wind and across-wind dynamic interference factor ( IFdx & IFdy ) contour maps are obtained, which could be used as references for wind load codes of buildings.
