抄録(和):
本論文では, まず非常に多くの自由度を有する鉄塔-架線系の架線方向の振動特性および地震応答を求めるための簡明で実用的な解析理論について述べ, 次に代表的な3つのモデルを選んで数値計算を行った. 選ばれた3つのモデルについては, いずれも架線との動的相互作用を考慮したニきの方が, 単体鉄塔の場合に比べて, 鉄塔に対する各種の応答(変位, 加速度, 部材応力) の最大値は小さくなるという結果を得た.

EFFECTS OF ELECTRICAL TRANSMISSION LINES ON EARTHQUAKE RESPONSES OF HIGHSTEEL TOWERS
|
抄録(英):
Numerous degrees of freedom are necessary for dynamic analysis of electrical towers-transmission lines system by the F.E.M.. An analytical theory for simply and practically calculating the vibration characteristics and earthquake responses of the system in the direction of transmission lines is proposed with consideration of the dynamic interactions between towers and transmission lines. In the proposed theory, the number of degrees of freedom is considerably reduced by means of regarding the transmission lines as springs connecting the towers and by using the substructure method. The earthquake responses of three typical models of the system are calculated. One of the principal conclusions is the following. In every case, earthquake response values of the towers obtained by takinginto consideration the interactions between towers and transmission lines are smaller than those of a single tower.
