摘要
采用隔震技术可以有效地减小上部结构水平地震作用效应,减轻结构和非结构构件的地震破坏,提高建筑物及内部设施和人员在地震中的安全性。为了研究结构设置叠层橡胶隔震支座后的隔震效果,本工程使用大型有限元软件Etabs建立隔震与非隔震结构模型,对结构在隔震前后的地震反应进行对比分析。结果表明:采用隔震技术后,结构的地震反应明显减弱,取得较好的隔震效果。为隔震技术在以后的工程实际中的应用提供一定的参考价值。
Adopting isolation technology can effectively reduce the earthquake effect of the upper structure level, reduce the earthquake damage of structure and non structure components, improve the building and internal facilities and personnel security in the earthquake. In order to study the isolation effect after setting up laminated rubber isolation bearings on the structure, this project uses a large finite element software Etabs to build seismic Isolation and non isolation structure model, and compares the seismic response of the structure before and after the seismic Isolation. Results show that after using isolation technology, the seismic response of the structure decreased significantly, and obtained good effect of seismic isolation. This can provide certain reference for the application of seismic isolation technology in the engineering practice in the future.
