Determining the peak spatial and resultant accelerations of tall buildings tested in the wind tunnel

This paper presents a frequency domain approach to determine the expected peak spatial (x, y, torsion) and resultant accelerations of tall buildings tested in the wind tunnel. Auto-spectra and cross-spectra are computed from the generalized force time series determined from measured wind tunnel data. Spectral analysis is used to determine the auto- and cross-spectra of the modal responses from which the covariance matrix of the modal responses …
