| Abstract: | In this paper is proposed an improved vertical coherrence function to simplify the instantaneous pressure measurement method for wind_induced response of high rises.The method is fairly effective while analyzed in combination with the random vibration theory even then using less advanved equipment and involving fewer wind tunnel tests.Main dynamic parameters such as the power spectral density for base overturning moments,root mean square response,and peak dynamic displacement and acceleration on the top.etc.are well within the error range as compared with the data published in related literature. |
