Active Control with Optical Fiber Sensors and Neural Networks. II: Experimental Verification

摘要

Experimental results for a full-scale steel frame structure with a smart active control system under shaking-table testing are presented. To this end, a full-scale steel frame structure with the proposed control system is examined under earthquakes simulated by a 5 m X 5 m shaking table with several representative earthquakes arranged to assess the performance and robustness of the proposed control system. Signals detected from fiber Bragg grating sensors showed superior performance to conventional strain gauges in structure surveillance. Experimental data recorded during earthquake excitation, for structural strain, also demonstrated the improved performance of the proposed control system over the traditional active control. Experimental results demonstrated that the control system can be applied to buildings after the whole testing process.
