Modern solution of tube telecommunication tower - problems, analysis and perspectives

Abstract

The paper emphasizes aspects that have to be addressed when analyzing monopole structures, such as vortex excitation occurring due to a repeating pattern of vortex shedding in the flow of air around a tower (von Kármán vortex street). The fatigue analysis is discussed in detail in the paper and it presents solutions that were introduced on the basis of the analysis results in order to reinforce certain areas of the tower (stress concentration in the vicinity of structural details required due to technological reasons).
