摘要
针对数字福建云计算中心(社会和企业云)工程,进行基础隔震设计与分析。根据结构隔震控制理论,采用非线性分析方法。首先基于ETABS软件建立三维模型,输入7条地震波进行弹性动力时程分析,对比隔震前后结构的动力响应,合理布置隔震支座及粘滞阻尼器。同时对模型进行罕遇地震下弹塑性验算,对结构的变形、能量等方面进行详细分析。结果表明,通过合理的基础隔震设计,能够显著减小上部结构的地震作用,增加结构延性,极大提高结构的抗震性能。
According to the project of digital Fujian Cloud Computing Center（ Society and Enterprise Cloud）,the base isolation design and analysis are carried out. Based on the theory of structure isolation control,nonlinear analysis method is adopted. Firstly,the three- dimensional model is built based on ETABS software,and the dynamic time history analysis of 7 seismic waves is carried out. The dynamic response of the structure is compared with the dynamic response of the isolated structure. At the same time,the model is analyzed under the rare earthquake,and the deformation,energy and other aspects of the structure are analyzed in detail. The results show that the seismic effect of the upper structure is significantly reduced and the seismic performance of the structure is greatly improved by the rational base isolation design.
