000015943 520__ $$2eng$$aThe work presented in this paper pretends to structure the main concepts associated with the design of a guyed tower. In this context, are presented the theoretical foundations and the essential steps for the various methods of analysis. This topic is therefore of major interest for Metalogalva (Trofa, Portugal), with which the authors collaborate and interact, since this industry complex of metallic constructions is also involved in the design and construction of tall telecommunication towers and pole structures. Two dynamic actions are essential for the guyed tower design: The gust effect of wind and the action of earthquakes. Therefore this paper presents various considerations and topics involved in the modeling of a 185 m height guyed tower, that enable to characterize their structural response. Since this is a slender structure it is was necessary to take into account the effects of second-order P-Δ analysis and also the nonlinear behavior of cables.
