| Abstract: | Nine models with different rectangular cross sections are tested in a wind tun nel to study the characteristics of the local wind force on high rise buildings . In this paper, wind tunnel test data have been analyzed to determine the local w ind force coefficients and power spectra which are varying in vertical direction of the models. The effects of structural aspect ratio and side ratio on the ch aracteristics of the local wind force coefficients and power spectra on tall bui ldings are also investigated. Some important conclusions are reached on the correlation of the local wind force in the end. |
