Abstract
This paper presents a study of power transmission self-supporting tower using the Spectral Element Method (SEM), with the aim of overcoming the current limits of dynamic analysis in medium and high frequencies. The numerical analysis performed through computational implementation investigates the vibrational response of the tower. The results are validated by comparing them with results obtained via the Finite Element Method (FEM). Due to SEM is formulated based on the exact solution method no need to discretize the continuous elements, which implies in low computational effort and time-consuming. The vibration response of the tower obtained by SEM and FEM are presented, and the cost involved in both approaches computed.
