Smart Isolation Control for Shear-torsional Coupled Seismic Responses of Frame Structure

研究了 ER/ MR智能隔震系统对框架结构地震反应的半主动控制。根据智能基础隔震的特点 ,建立了基于模糊控制的半主动控制策略。仿真计算表明智能隔震系统不仅能够显著减小上部结构的地震反应 ,还能够有效地保护隔震层的变形 。

In this paper, the smart isolation control systems consisted of ER/MR dampers and isolators are studied for earthquake response of frame structure. According to the property of smart isolation system, the semi active fuzzy control method is established in this study. Simulated analysis demonstrates that the smart isolation system can not only significantly reduce the earthquake responses of upper structure, but also effectively protect the deformation of isolation layer. Thus, smart isolation system had the potential to become a practical and useful control system.
