Power Spectra of Across-wind Loads on Super High-rise Buildings

models with different figures were tested with a high frequency force balance (HFFB) technique in 4 types of windfields in a wind tunnel to study the effects of windfields,models' aspect ratio,side ratio,corner cut and recession on the across-wind load of super high-rise buildings.A close equation of the power spectra of across-wind loads on super high rise buildings has been obtained by curve fitting method,and has been verified by the results from the present wind tunnel test and other literatures.
