本研究は,鉄塔と送電線相互作用を考慮した超高電圧送電鉄塔の地震応答解析法を示したものである. 本解析法は, 鉄塔と送電線の地震応答を鉄塔のみの振動特性および送電線の振動特性を用いて両者の連成振動として, それぞれに振動形解析法を適用して解く方法であり, 送電線群を鉄塔群に結合したばねと見なして解析する方法に比べて,その地震応答計算の信頼性は高いといえる. キーワード(和): 送電塔,送電線,地震応答,応答解析,相互作用,連成振動,信頼性 掲載雑誌(英): JOURNAL OF STRUCTURAL MECHANICS AND EARTHQUAKE ENGINEERING 著者(英): Seima KOTSUBO,Teruhiko TAKANISHI,Katsushi IJIMA,Kiyoshi UNO タイトル(英): A METHOD OF RESPONSE ANALYSIS OF TOWERS AND TRANSMISSION LINES SYSTEMS SUBJECTED TO EARTHQUAKES 抄録(英):
This paper presents a method of response analysis of ultra-high-voltage towers subjected to earthquakes, taking into consideration the interaction between towers and the transmission lines. Seismic responses of them are solved by the method of model analysis using individual natural vibration characteristics ofeach tower and transmission line. This method has the advantages as follows : 1) The degrees of freedom remarkably decrease, as compared with those in the method applying the F.E.M. to the towers and the transmission lines. 2) This method can be applied, without difficulty, to the case where seismic waves differ at each foundation of tower and to the case where suspension towers are included. 3) The results obtained by this method are more accurate than those obtained by themethod regarding the transmission lines as springs connecting the towers. キーワード(英): - 記事区分 投稿論文 区分     論文集
