The WAWS (weighted amplitude wave superposition) method, one of stochastic field simulation technologies, and finite element technology is combined to generate fluctuating wind field and further make buffeting response analysis of one container crane under the assumption of quasi-steady flow. The disturbing wind field simulation indicates the PSDs of the simulated samples agree well with the targets except the low frequency band of the auto-spectrums. Furthermore, displacement response spectrum of the front beam endpoint presents tha the fluctuating wind can excite greatly the first mode of the crane. It is worth while to note that maximum displacement of the endpoint reaches 53mm under the along-wind field and probably excites coupled vibration between the electric vehicle and the railway on the beam, which in- fluences the vehicle running safety. However, both lateral and vertical displacements are so small as to be neglected.
