摘要

本文研究开发了一种新型的高阻尼比减隔震支座，设计了一个与实际工程结构相接近的Y字型巨-子结构钢模型，并分别对传统巨-子型结构抗震体系和采用新型减隔震支座连接的控制体系进行了振动台试验。结果表明，与传统的巨-子型结构抗震体系相比，新型的巨-子结构控制体系在地震作用下的反应显著降低，具有良好的减震效果。由试验观察到的该控制体系减震机理与理论分析结果相吻合，可为工程设计和应用提供参考。

Abstract

In this paper,a novel isolation device with high damping ratio was developed and introduced.Base on a designed Y style mega-sub steel structure model closed to a real engineering,the shaking table tests of the traditional mega-sub anti-seismic system and the new mega-sub control system set by the novel isolation devices were carried out separately.The results show that the response of the mage-sub control system under earthquake excitation is much less than that of the traditional mage-sub anti-seismic system and can be controlled well.The seismic reduction mechanism of this control system observed from the experiment is identical with the result from theoretical analysis.The conclusion of the research can be used as a reference for engineering design and application.
