| 概要 |
We investigated the dynamic properties of a transmission tower with reinforced arms by members installed to reduce axial force of horizontal tie members, and its wind resistant performance of the towe...r under strong winds was reported. The dynamic properties of the single tower were analyzed using the natural frequency and frequency response techniques, and the wind resistant performance of some tower-and-cable coupling models was investigated using the spectral response methods and step-by-step integral techniques. As a result, it was found that the reinforcing member can reduce the axial force of the horizontal tie member. Finally, we confirmed the reducing rate of the force is about 90% and 70% against mean wind loads and dynamic wind loads, respectively.続きを見る
