隔震支座在大跨空间结构中的应用与发展

Application and Development of Seismic Isolation Bearings in Large-span Spatial Structures

文中简要叙述了隔震技术在大跨空间结构的应用及原理,介绍了目前在大跨空间结构中应用最多的橡胶隔震支座和摩擦摆隔震支座,并论述了这两种支座的局限性,进一步分析和整理了新型三维隔震支座在大跨空间结构中的应用及存在的问题。目前,新型三维隔震支座在实际工程中的应用比较少,其在实际工程中隔震效果的有效性还有待验证。

This paper briefly describes the application and principle of seismic isolation technology in large-span spatial structures,introduces the most widely used rubber seismic isolation bearings and friction pendulum seismic isolation bearings in large-span spatial structures,and briefly explains the limitations of these two supports.The application and existing problems of the new three-dimensional seismic isolation support in the large-span spatial structure are further analyzed and sorted out.At present,the application of the new threedimensional seismic isolation support in practical engineering is relatively small,and the effectiveness of its seismic isolation effect has yet to be verified in actual engineering.
