Intelligent Isolation Control for Seismic Response of Structure

The intelligent isolation control systems consisted of ER/MR damper and isolator are studied for earthquake response of structure. Based isolation systems can change the characteristics of structure system and significantly reduce seismic energy to upper structure. ER/MR damper can improve effectively the performance of passive isolation system and protect deformation of isolation layer against damage. According to the property of intelligent isolation system, the semi active control method based on instantaneous optimal control is established in this study. Simulated analysis demonstrates that the intelligent isolation system can not only significantly reduce the earthquake response of upper structure, but protect effectively the deformation of isolation layer, intelligent isolation system had the potential to become a practical and useful control system.
