Abstract
In a country with continental dimensions such as Brazil, energy distribution networks are of the utmost importance. These networks are composed of transmission towers of various sizes and characteristics. Accidents with these structures can cause several disorders, as well as endangering the lives of many people. Therefore, the study of the dynamics of these structures is fundamental. This work aims to study the natural frequencies of a tower model (suspension tower) and its behavior when inserting viscoelastic materials into the structure, in the column connections thereof, to introduce damping in the structure. The study was carried out using the finite element method (FEM) through commercial software SAP2000, considering a transmission tower modeled as a space trellis. The use of viscoelastic material at the junction of the tower columns is efficient in terms of the damping introduced into the structure.
