带智能磁流变阻尼器的层间隔震混合控制研究

Hybrid Control of Mid-story Isolation with “Smart” MR Damper

为了进一步提高层间隔震体系的整体抗震性能,提出在层间隔震体系中附设MR智能磁流变阻尼器控制装置,构成新型的混合层间隔震控制体系。通过对某实际工程算例的非线性仿真分析,系统地研究了这种新型混合智能层间隔震控制体系的有效性,并与传统被动层间隔震减震效果进行了对比。

This paper presents a new type of hybrid mid-story isolation control system in which ＂Smart＂ MR magnetorheological damper is employed, in order to further improve the overall seismic performance of the mid-story isolation system. Through the non-linear simulation analysis of a practical engineering example, this new type of hybrid mid-story isolation system is shown to achieve notable decreases in earthquake responses compared with the passive counterpart.
