description abstract | An overhead transmission line system is a typical wind-sensitive structure with high flexibility, light weight, and low structural damping. Wind-induced dynamic reaction of the transmission line system is a determining factor in structural design of the supporting tower. In this study, we employ a closed-form solution and a series of wind tunnel tests to investigate three-dimensional dynamic reaction of transmission lines bundled with an insulator in three types, including I-type, V-type, and strain-type. The response comprises the background and resonant component. It is found that the background component constitutes a major part of the response, and the resonant component is closely related to the first symmetric out-of-plane mode. Furthermore, the closed-form solution is discussed and validated by the aeroelastic wind tunnel testing in the frequency domain. Based on the experimental data, this study provides a theoretical method for predicting wind-induced loads on transmission tower structures. | |
