| Abstract | This paper outlines the methods that have been used to determine the frequencies and modes of vibration of multistory buildings from their wind-induced vibrations. Three buildings of ten, thirty-eight and forty-seven stories were investigated. A simple theoretical models was used to calculate the frequencies of vibration of the buildings; the models was based on the assumption that there was no joint rotation in the building frames. A comparison of the theoretical and measured values of the frequencies showed that this simple models was a realistic representation of only the smaller building. It is concluded that a models that includes joint rotation would be more realistic for the taller buildings. Autocorrelation and power spectrum analysis of the vibration records were used to obtain an estimate of the damping characteristics of the buildings. The values obtained were 1 to 3 per cent of the critical amount of damping. |
