本文では,基盤における強震動波形の統計的予測モデルを作成するため,強震記録の非定常スペクトル特性に注目し,それを統計解析した。その結果,強震動の非定常スペクル特性は4つのパラメータをもつモデル関数で示せること,このパラメータの重回帰分析から非定常特性が地震諸元から受ける影響が定量的に求められること等が明らかとなった キーワード(和): 強震;地震波;基盤岩層;統計解析;統計模型;スペクトル線形;多重回帰分析 掲載雑誌(英): JOURNAL OF STRUCTURAL MECHANICS AND EARTHQUAKE ENGINEERING 著者(英): タイトル(英): A STATISTICAL MODEL FOR PREDICTING STRONG EARTHQUAKE MOTIONS OF BED ROCK 抄録(英):
A prediction technique of bed motions during strong earthquakes is studied using strong-motion accelerograms obtained at ground surface. The method is not due to the earthquake response analysis of soil layers, which is employed in general, but due to a statistical technique by which the nonstationary spectra of strong-motion earthquake records are scaled with the earthquake factors and local soil conditions. Itis shown from the statistical analysis how the nonstationary characteristics of earthquake motions are affected by the factors of earthquake source as well as local soil conditions. By using the technique presented here, possible motions of bed rock can be estimated provided that the earthquake factors such as magnitude, focal depth and epicentral distance are available, andthey agree comparatively well with recorded motions. キーワード(英): - 記事区分 投稿論文 区分     論文集
