Abstract
An analytical model based on quasi-steady assumption of wind loading is formulated to assess the galloping of slender towers that are nonlinearly coupled in two directions about the principal axes. To illustrate the effectiveness of this model, it is used to evaluate the responses of a full-scale slender tower subjected to excitation from winds simulated using the spectral representation method. Some of the numerical results are compared with field observations of wind-induced galloping oscillations of this tower. The characteristics of the oscillations, including the root mean square (RMS) amplitudes and the kurtosis, and the dependence of these characteristics on the mean wind speed and the turbulence are presented.
