Topological analysis of cables in a model of guyed tower

Abstract

Guyed towers are structures commonly used in the area of telecommunications for support antennas at high altitudes. The failure rate of this structural type with respect to others of similar complexity is high. Many factors are involved in the structural behaviour under the action of extreme winds. Cable topology (number of cables in the shaft, angle of cables respect to the shaft, number or anchors), tension of cables and torsion reduction systems are very significant in the response of these structures to wind forces. This study aims to investigate the effect of the topology of the cables and the torsion reduction system on the structural behaviour of a typical tower model using the finite element method with the SAP2000 software, taking into account the dynamic characteristics of the wind load and the non-linearity of the structure.
