Summary

This paper addresses the main concepts associated with the design of a guyed tower. In this context, the theoretical foundations and the essential steps for the various methods of analysis are presented. This topic is therefore of major interest for Metalogalva (Trofa, Portugal), with which the authors collaborate and interact, since this developer 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 the 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 is able to characterize its structural response. Since this is a slender structure it was necessary to take into account the effects of a second-order P-delta analysis and also the nonlinear behavior of the cables. The control of vibrations of the guyed tower was accessed, but it was understood that the six-guy cables modeled as catenaries already constitute vibration control devices that dampen structural response.
