Streszczenie

Computational determination of aerodynamic resistance for high truss structures like telecommunications towers is the subject of this study. Normalized procedures were presented with an example of an existing structure concerning the total wind coefficient. The results of calculations along with their broad elaboration and interpretation have been presented. Analyses and calculations were conducted for a tower of height equal to 84 metres and of a triangular cross section. The structure is characterized by round full rods as the legs of the tower and hot-rolled angle bars as the bracing. Two computational approaches were applied providing the results for each of them. The achieved results allow for stating that selection of a computational standard procedure should be adequate to an analysed structure and its characteristic features. The information included in the article is particularly useful in case of the determination of carrying capacity of existing tower structures on the basis of Eurocode standards.
