オンライン・オフライン併用データ処理による建築物と地盤の常時微動特性の推定 : 常時微動測定を用いた既存建築物の地震脆弱性評価その1

概要

論文の詳細を見る
A methodology is presented for the evaluation of vibrational characteristics of existing buildings and underlying soil using online and off-line combined data processing, On-line processing is based on microtremor measurements. Predominant periods and damping ratios are evaluated by Fast Fourier Transform in the frequency domain and by random decrement technique in the time domain. Off-line processing is based on existing empirical equations and simplified theoretical models, taking into account the statistical variability of model parameters. On- and off-line results are compared with each other and updated to get more refined and reliable results. Examples are presented to show the applicability of the proposed method.
