橡胶支座隔震技术在灾区重建工程中的应用

Reconstruction engineering application of rubber bearing isolation technique in disaster area

隔震结构体系是区别于传统抗震结构体系的一种被动控制体系,通过设置隔震层来吸收并消耗地震能量,减小结构的地震反应,确保结构的安全。本文通过采用橡胶支座隔震技术的四川某灾后重建工程实例,运用时程分析法对隔震结构的地震反应进行了计算分析。分析结果表明,隔震结构在罕遇地震作用下仍处于弹性工作状态,结构具有较好的抗震性能。本文同时介绍了橡胶隔震支座的施工工艺及注意事项,希望对今后类似工程有一定借鉴作用。

Seismic isolated structure system is a passive active control system, which is different from traditional anti--seismic structure system. Through setting isolation layer, earthquake energy is absorbed and dissipated and earthquake response of structure is reduced, so that the safe of structure is ensured. In this paper, the seismic response of isolated structures in an earthquake reconstruction project in Sichuan using rubber bearing isolation technique is calculated and analyzed by time history analysis method. The results show that isolated structures is still in elastic state under rare earthquake and the structure has better seismic performance. This paper also describes the construction technology and points for attention of rubber isolation bearings, hoping to have a certain reference for future similar projects.
