摘要
实际震害表明,建筑物主要受水平地震作用影响,本文采用大型有限元软件ANSYS建立十层基础隔震框架核心筒结构和非隔震结构实体模型,并采用时程分析方法对此模型进行了单向水平地震作用分析。结果表明,框筒结构采用基础隔震技术之后,水平地震反应明显降低。
The actual earthquake damage shows that the role of buildings in the earthquake affected mainly by the level of this paper,using ANSYS finite element software framework for the establishment of 10 base-isolation layer of the core tube structure and non-isolated structures with physical models,and using time-history analysis method This model was one-way analysis of horizontal seismic action.The results show that the framework of the core tube structure with base isolation technology,the level of seismic response decreased significantly.
