项目摘要

In this study, active control system of buildings for severe earthquakes are developed and seismic response control experiments using a full-scale structure and a structural model by using a shaking table were performed to verify the structural control systems.1)The methodologies for the identification of structural parameters and estimation of structural responses were studies. The subspace-based system identification method was introduced. To certify the identification results, seismic vibration experiments under real earthquake were performed. 2)The specimen stucture utilized for structural control experiments is a five-story steel frame built in the Uji Campus of Kyoto University. To realize seismic motions of the specimen structure as if under earthquake, the earthquake response generator system was developed by using two excitors installed on the 5th and 3rd floors. Vibration tests of the full-scale structure demonstrate the accuracy and validity of the earthquake response genera … More tor system. 3)Seismic control experiments of the specimen structure with a AMD (Active Mass Damper) were conducted by using control algorithms based on LQ/LQG control theory, the pole assignment method and the H^* control theory. The effectiveness of the designed controllers were illustrated through seismic vibration experiments of the full-scale specimen structure by using the earthquake response generator system. 4)Seismic control experiments using an structural model specimen with rwo AMDs were also performed by using a shaking table. The stability and robustness of control algorithms were verified. 5)To develop algorithms that can control the AMD within its stroke limitation is an important problem in order to apply the AMD system to seismic response control for severe earthquakes. The algorithms with variable control gain were developed. Experiments using the full-scale test structure and Shaking-table experiments using the structural model specimen were perfomed. It is emphasized that the structural control systems have a feasibility of controlling buildings even during severe earthquakes. Less
