Ｅ－ディフェンスによる既存不適格建物補強・無補強実験 E-Defense Experiments on Existing Non-compliant Wooden Houses with and without Reinforcement 防災科学技術研究所 ボウサイカガクギジュツケンキュウショ National Research Institute for Earth Science and Disaster Resilience 防災科学技術研究所 ボウサイカガクギジュツケンキュウショ National Research Institute for Earth Science and Disaster Resilience 文部科学省『大都市大震災軽減化特別プロジェクト』の一環として、建築基準法が大幅に改正された1981年以前に建てられた木造住宅の実験を行いました。構造が類似する2棟の実在物件を、西明石からＥ－ディフェンス震動台上に移築して、1棟はそのままの状態（補強無し住宅）、もう1棟は金具や構造合板、筋交いなどを用いて耐震補強した状態（補強住宅）で、兵庫県南部地震の観測地震動を入力しました。その結果、木造住宅が倒壊に至るまでの詳細なデータを取得し、今回の実験で採用した耐震補強方法の効果を検証することができました。 As a part of “Special Project for Earthquake Disaster Mitigation in Urban Areas” supported by Ministry of Education, Culture, Sports, Science and Technology (MEXT), an experiment was conducted on wooden houses built before 1981, when the Building Standards were substantially revised. Two existing houses with similar structures were moved from Nishi-Akashi City onto the E-Defense shake table, with one house left as it was (the unreinforced house) and the other reinforced with metal fittings, structural plywood and diagonal braces (the reinforced house). The observed seismic motion of the Hyogo-ken Nanbu Earthquake was input into these two houses. As a result, detailed data was obtained on the progress of the collapse of the wooden house, and the effectiveness of the seismic reinforcement method adopted in this experiment was verified. データ取得：2005年 Data acquisition period : 2005 お問い合わせ：asebi@bosai.go.jp inquiry： asebi@bosai.go.jp 防災科学技術研究所 National Research Institute for Earth Science and Disaster Resilience 2025-04-16 dataset 10.17598/NIED.0020-E200505 https://nied-repo.bosai.go.jp/records/7146 https://asebi.bosai.go.jp/ LOGIN Page for Registered Users
