It brings simple and practical calculation method and the theoretical results are compared with long-term measurements on several existing structures. Wind load has been described taking into account the probability distribution function of the mean velocity and corresponding wind pressures. The dynamic response of structure is caused by the turbulence described with a spectral model both for longitudinal and lateral direction. Structural response takes into account the contribution of more vibration modes. Based upon this knowledge, the number of cycles during certain period was determined. The fatigue analysis has been carried out and the residual time life prediction of antennas was determined for an industrial partner.
