Evaluation on Dynamic Responses of Transmission Lines Subjected to Wind Excitations

Abstract:

The evaluation on dynamic responses of transmission lines subjected to wind excitations is actively carried out in this study. A transmission tower-line system constructed in the southern coastal areas of China is taken as example to examine the wind induced response of the transmission lines. The structural model is established based on finite element approach by using commercial package. The displacement, velocity and acceleration responses of the transmission lines are computed to explore structural performance. The made observations indicate that the transmission lines vibrant substantially when subjected to strong winds. It is obvious that the dynamic responses of the ground wire are smaller than those of the wire and the responses in the long span are much larger than those in the short span.
