Analytical study on wind-induced vibration of power transmission tower

概要

論文の詳細を見る
Since power transmission towers tend to be sensitive to wind action as a function of size and shape, it is very important to accurately estimate their response to strong winds and take this into account their design. However, power transmission towers are connected with power lines, which show geometrically nonlinear behavior and have many complex vibration modes whose frequencies are normally very close. On the other hand, it has been shown that the characteristics of wind-induced vibration of a power transmission tower are strongly influenced by the behavior of power lines.<BR>This study describes an analytical method for wind-induced vibration of power transmission towers coupled with power lines and results of two case studies. Further, it discusses the influence on response characteristics resulting from differences in transmission support systems and differences between peak factors, computed from a time-series and from power spectrum density.
