Wind load and wind direction effect on lattice antena tower

This paper describes experimental system for determination of stresses on a mobile antenna tower caused by the wind load. For this purpose a lattice antenna tower was equipped with the sensory system for measuring strain and meteorological (i.e. wind’s speed and the wind direction) data in the Dalmatia region. The service load’s spectra was determined based on experimental measurements which depended on the most influential winds Bora and Sirocco for its respective wind epochs. Based on results obtained during the field testing, the methodology for determination of the service spectra from bending moment’s scatter plot diagram, which results with the LCC of service spectra, is proposed.
