| 摘 要： | 广东科学中心E区结构体型复杂,刚度和质量在竖向分布不均匀,导致结构扭转效应比较明显.本文结合结构设计提出了五种隔震控制方案.利用SAP2000有限元分析软件,对采用不同控制方案的结构进行了模态分析和时程分析,对比分析了不同方案的控制效果.分析结果表明,采用隔震技术不仅大大降低结构的地震反应,也使结构的扭转效应得到有效的控制.依据分析结果对该工程隔震支座的布置提出建议.

| Abstract: | The district E of the Guangdong Science Center is a complex structure,in which the torsional response is significant due to stiffness and mass non-uniform distribution in vertical direction.Based on the original structural design,the five base-isolated schemes are proposed to solve the above problems.The modal analysis and the time-history analysis for different schemes with SAP2000 finite element analysis software are completed.The analysis results show that the structural earthquake responses can be obvio... |
