Lifetime prediction of wind loaded mast and towers with respect to lateral and longitudinal wind spectrum

Abstract eng:
The paper describes an analysis for the purpose of theoretical lifetime prediction of telecommunication towers, guyed masts and antenna’s extensions. 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.
