Research Abstract	地震時に被害を受けた構造物や経年的劣化を伴う構造物の健全度をモニターする計測・解析システムの開発と構造物の信頼性の向上させるための次世代システムを開発することを目的として、研究分担者3名に研究協力者5名を加えて実施している。 1)構造物の非線形同定法の開発:構造物の非線形動力学特性を同定する目的で,忘却機能を有する最小2乗法とカルマンフィルターによるアルゴリズム、H無限大フイルタリング手法,推定誤差法(PEM)、ウエーブレット手法,ブートストラップ・モンテカルロフィルター手法を用いて非線形システム同定アルゴリズムの開発を行った。 2)構造物の健全度モニタリングシステムの開発:超音波やアコースチック・エミションによる構造物の損傷検出システム技術の開発を行った。また、炭素繊維の導電性を利用したCFRP複合材料を用いて最大歪記憶型パッチセンサの技術開発を行い、最大歪などの計測が可能となった。 3)構造物の地震時損傷評価法の開発:構造物系に含まれる不確定性を考慮した地震時損傷解析法として、確率微分方程式を用いた定式化による方法を開発し、復元力特性を有する非線形構造物系に適用した。構造物や破壊規範に含まれる不確定性が構造物の地震応答や信頼性に大きく影響することが指摘された。 4)構造物の信頼性向上のための技術開発:制御装置の許容限界を考慮した非線形制御アルゴリズムを開発し振動台による制震実験によって制御アルゴリズムの検証を行った。大地震時には、このような非線形制御アルゴリズムが有効であることが分かった。また,伝統的木造建築物の構造メカニズムの解明とダンパー等による耐震性能の向上を目的とした実大振動実験を実施し、伝統的木造建築物は地震時の揺れに対応する機構を有している、さらに制震装置の導入により地震時応答を低減することが可能であり、今後、より有効な構造制御法の開発に期待される。
