结合新规范分析我国高层隔震技术研究现状及新问题

Combining the new code to analyze the research status of high-rise isolation technology and some new problems

近年来,隔震技术作为一门新兴的被动减震技术,在我国工程领域引起了广泛关注。而其中的高层隔震技术由于诸多理论研究的不完善使其推广受限。国内高层结构隔震技术的研究主要是针对基础采用橡胶垫隔震支座的高层结构,研究的主要方向有高层减震性能分析、等效简化模型、支座受拉原理及应对措施、高宽比限值等,并在这些方向上取得了一定的成果。结合新规范对这些成果进行了分析与综述,提出了一些还处于初步阶段的问题,为高层隔震技术进一步的研究提供了平台,也对这一技术的发展有着积极的推动作用。

In recent years,base-isolation technology which is a new type of passive damping technology has aroused widespread attention.But its application in high-rise buildings has been limited due to incomplete theoretical research.The domestic research usually concentrates on the performance of this technology,equivalent model,confirmation of aspect ratio and so on.This paper,combining the new design cord for seismic isolation,concludes the results on these aspects in brief,and introduces some unresolved problems hoping to bring more attention to this technology.
