Wind load and wind direction effect on lattice antena tower

The presented paper describes experimental system for determination of stresses on mobile antenna tower caused by wind load. For this purpose lattice antenna tower, in region of Dalmatia, was equipped with sensory system for measuring strain and meteorological (wind speed and wind direction) data. From experimental measurements service load spectra, depending on the most influential winds Bora and Scirocco, are determined for characteristic wind epochs. Methodology for determination service spectra from scatter plot diagram of bending moment, which result with LCC of service spectra, is proposed.
