In this study, the development and shake table test of hybrid controlled bridge-isolation system are presented. The hybrid controlled bridge-isolation system is composed of the rolling pendulum system and the smart MR damper. The rolling pendulum system provides the suitable restoring force, and the smart MR damper provides the online adjusted hysteretic force. The scaled-down bridge model is used in the shake table test. Both passive and semi-active control cases are compared in this study. According to the shake table test results, the hybrid controlled bridge isolation system can reduce the deck acceleration effectively with the limited stroke. Also, it is stable and adaptive to different intensity of excitation. |
