Hybrid experimental method, in which a vibration experiment using an actuator and a vibration analysis using a computer are simultaneously conducted by exchanging information with each other, is being developed as a new seismic experimental method. We developed a real-time hybrid experimental system using a hydraulic actuator with large excitation capacity and used it in a seismic experiment of an energy absorber. This absorber is a new type of pipe-support absorbing vibration energy by elastoplastic deformation By comparing the results of the hybrid experiment with those of the shaking-table experiment, we showed that the results obtained by the two experimental methods were close to each other. Therefore reliability of the developed hybrid experimental system was verified.
