某高层建筑基础隔震设计

The Base Isolation Design of A High Building

近年来随着隔震技术的日益成熟,隔震技术越来越多地应用到高层建筑中。本文以某新区一采用基础隔震的高层建筑为例,应用ETABS三维有限元程序建立实体模型,通过振型分析和时程分析,研究不同地震波作用下其抗震性能,并对其进行隔震优化设计。

In recent years, the isolation technology has been recognized as a mature technology, and was used in more and more high buildings. In this paper, a base-isolation high building locating at a new district is taken as an example. A 3D finite element model is established by ETABS. Then, mode and time-history analysis are separately used to analyze the seismic performances of the high-rise building under the actions of different seismic waves. The isolation design of the building is optimized eventually.
