Abstract |
建物内の設備機器と連携して地震時の機能維持を図る高度な制震システムを開発した。設備機器と無線通信を行いビデオカメラの映像をもとに応答を制御する手法を構築した。また, 建物の地震応答情報をもとに構造パラメータを同定し, 被害発生確率を最小化するよう制御系設計を行い制御性能を向上する方法を提案し, 実在するセミアクティブ免震建物に適用した。被害発生確率の評価に用いる模擬地震動の作成手法に関して, 震源が近い地震の地震波形が類似することを考慮した数理モデルを構築した。そして, 研究の過程で地震動を受ける建物が水平変位に直交する慣性力によってねじれの共振現象を引き起こしうることを発見した。
We have developed an advanced seismic control system that maintains the functions during an earthquake by coordinating with the equipment inside the building. We constructed a method to control the response based on the video by wireless communication with the equipment. In addition, we proposed a method to identify the structural parameters based on the seismic response data of the building, design the control system to minimize the damage occurrence probability, and improve the control performance, which was applied to the existing semi-active seismic isolated building. Regarding the earthquake motion simulation method, we constructed a mathematical model considering that the seismic waveforms of earthquakes with closely located hypocenters are similar. Finally, we discovered that a building subjected to seismic motion could cause torsional resonance due to inertial force perpendicular to horizontal displacement.
