Torsional-vertical seismic response control of multi-story structure with intelligent compound base-isolation system
【摘要】 本文在提出了"碟形弹簧-橡胶隔震垫"和MR阻尼器组合而成的智能复合隔震系统的基础上,建立了智能复合隔震系统对多层建筑结构"水平剪扭-竖向"地震反应控制的设计计算方法。提出了智能复合隔震系统对建筑结构水平地震反应的模糊半主动控制策略和对建筑结构竖向地震反应的被动控制方法。以一个五层框架结构为例进行了仿真分析。分析结果表明,本文提出的智能复合隔震系统是一种十分简单和有效的隔震系统。它可克服建筑结构常规隔震系统的两个主要缺点,有效地抑制多层建筑结构的多维地震反应。
【Abstract】 The intelligent compound baseisolation system consisting of disk spring, rubber isolator and magnetorheological (MR) damper is proposed in the paper. According to the mechanic characteristics of the system, the computational method of torsionalvertical seismic response control of multistory structure is established. Then fuzzy semiactive control strategy is proposed to control horizontal seismic response and passive control method is used to reduce the vertical response. Taking a fivestory frame structure as an example, an extensive simulation analysis is carried out. The numerical results show that the proposed intelligent compound baseisolation system can overcome two inherent defects of common baseisolation system and effectively reduce multidimensional seismic response of the structure.
