某教学楼基础隔震结构分析与设计

Design of Base-Isolation for a Teaching Building

采用结构设计软件盈建科(YJK)对高烈度区某教学楼进行了多塔大底板基础隔震结构分析与设计。结果表明,在上部多塔+整体底板时采用基础隔震结构依然能显著减小上部结构地震作用;通过各类支座合理设计并配以少量阻尼器,能较好地降低结构平面不规则而产生的扭转问题,很适合高烈度地区使用。该工程主体结构已基本完工,本文可供同类工程设计参考。

The base isolated structure of a multi-tower building with unified base-floor is analyzed and designed by YJK.The analysis results show that the base isolated structure can significantly reduce the earthquake action of the upper structure.With bearings and dampers reasonably used in the design,the torsion caused by the irregular structure plane can be reduced.Base isolation of multi-tower building is very suitable for use in high intensity areas.The main structure of the project has been basically completed.This paper can be used as a reference for the design of similar projects.
