附加间隙式阻尼器复合隔震体系研究

The research of compound isolation system with the gap-damping

本文介绍了一种特殊复合隔震体系,与传统的复合隔震体系的不同之处在于除采用叠层橡胶支座和摩擦滑移支座外,附加使用一种新型的隔震支座-间隙式阻尼器。通过算例计算分析证明了该隔震体系能大大减小上部结构的反应,有效地控制了隔震层的位移,提高了建筑物的抗震能力,获得更佳的技术和经济效果。

This paper introduces a special compound isolation system different from the traditional compound isolation system. It uses a new isolation style -- gap damping in addition to adopting rubber and frictional slipper isolation. Analysis by example proved that the new isolation system would greatly reduce the response of the upper structure. At the same time it controlled the displacement of the isolation layer in a reasonable range, improved seismic capacity of building. And access better technical and economic effects.
