Resumo

Throughout the last decades, there was a great increased in a production of electricity. The production process is divided into generation, transmission and distribution. The Brazilian energy matrix is based mostly on hydroelectric generation. For the large territorial extensions, is natural that the power plant was be building away from the more important downtown's, and the transmissions systems need be large for ensure meeting the demand at low cost. Therefore, this paper intends to carry out the construction of an experimental model for a transmission tower, in scale, in order to feed the numerical model with data and calibration and show the modal behavior of this equipment. The performed experimental modal analysis provided consistent results for the modal parameters of the constructed tower, allowing the construction of a numerical model still valid and will provide the basis for graduation courses and graduate, as General Mechanics and Experimental Modal Analysis.
