Abstract | Steel lattice towers are widely used for supporting telecommunication antennas. Herein, a performance-based analysis of a 48 m steel lattice telecommunication tower is presented. The tower has been designed according to the Eurocode requirements for coastal areas of Greece considering a basic wind speed value of 33 m/s. First, the fragility assessment (probability of failure) of the particular tower against various combinations of wind speed
and direction is carried out. Then, after elaborating time series of wind data from selected islands or coastal regions throughout Greece and based on the resulting wind speed and direction distributions, the corresponding risk of the tower is calculated for each location and the results are displayed on the geographical map of Greece. In practice, the above procedure introduces a framework for evaluating the performance of steel lattice towers against extreme wind. The present framework can be elaborated as a useful tool by mobile phone companies in the context of planning and/or upgrading their networks. Furthermore, by assessing and comparing the resulting risk levels of the various locations (coastal regions), inferences about the validity of Eurocode National Annex assumption for a single basic wind speed value of 33 m/s for all coastal regions in Greece can be derived.
