Lifetime prediction of wind loaded mast and towers with respect to lateral and longitudinal wind spectrum
Original language description
The paper deals with a theoretical lifetime prediction of telecommunication towers, guyed masts and antenna?s cantilevers and comparison with the long-term measurements. A simple and practical calculation method is presented. The wind load is described taking into account the probability distribution function of the mean velocity and corresponding wind pressures. The dynamic response of structure caused by the turbulence uses wind models for both longitudinal and lateral direction. Structural response takes into account the contribution of more vibration modes. Based upon this knowledge, the number of cycles for certain time period together with the residual time life prediction of antennas cantilevers and cables was determined.
