Outline of Annual Research Achievements

最終年度は,下記の4点に焦点を当てて研究を実施した.[一体打ちRC壁]と[袖壁や方立壁]に関しては,壁パネルと隣接する柱における変形集中の度合い,コンクリートの損傷程度を定量化する目的で,実大5層建物実験のFEM解析を行った.これまでに蓄積した曲げとせん断ひび割れに関する知見を検証し,ひび割れに関して幅・数や長さなどに関しての予測精度を高めることができた.[圧着型PCaPC壁]に関しては,本研究課題で行ったダンパ-付ロッキング壁の実験結果詳細解析に基づいて損傷評価を行った.また,耐震壁脚部における変形集中の度合いや材料の損傷程度が,軸力から受ける影響について考察を行った.解析結果に基づいて,損傷や限界状態を制御性能な高性能ロッキング壁を提案した.[損傷予想解析モデルの開発]に関しては,本研究グループで昨年から開発を進めたせん断バネを付加したマルチスプリングモデルを応用して曲げやせん断のひび割れに関する予測精度を高めた.計算モデルの検証は,実験を終えた実大建物モデル(建築研究所)および2次壁(東工大)の実験データを活用して行った.
最終年度であったため,本研究の全体成果をまとめ論文(建築学会構造系論文集)や国際会議(ヨーロッパ地震工学会議ECEE,米国地震工学会議NCEE)で発表した.今後は国内での提案システム実用化を図るため,企業との共同研究を通じて具体的な設計方法を確立する.また,建築学会PC運営委員会においてアンボンドPC構造物の設計指針を刊行するための委員会活動を進め,本研究成果を社会に還元する.
