Abstract
The dynamics of Tower Crane is complicated by wind excitation which complicates the wind-induced
vibration response analysis. The random wind-induced response analysis of tower crane is presented based on finite
element method and virtual excitation method. The pulsating wind loads change into multiple-point correlation stationary
excitation. This paper uses Davenport’s wind speed spectrum which does not change with height, and considers multiplepoint
correlation of wind-induction. The tower crane was employed as a numerical example; the response spectra and
Mean Square Root (RMS) of the tower crane were obtained by wind-induced vibration. The results indicate that the
vibration of the tower crane showed a greater response in low frequency with the One-third Octave acceleration RMS
being lower. Finally, the influences of the wind-induced vibration on comfort were analyzed.
