西南某应急救援中心技术业务楼隔震设计

Seismic isolation design for a technical building of a emergency rescue center in southwest China

通过某中心技术业务楼隔震设计实例,全面介绍了按《建筑隔震设计标准》进行隔震设计。本楼选择基础隔震,采用LRB和LNR隔震支座;对全楼设定抗震性能目标,对结构构件区分关键和普通构件并设定相应的性能水准。采用结构分析软件YJK 5.2,对结构进行反应谱和时程分析。通过分析结果对比,本楼的隔震方案合理,可以显著降低上部结构的地震反应。本工程为隔震技术在类似建筑中的广泛应用提供了一个良好实例。

Based on an example of seismic isolation design for a central technical building,this paper comprehensively introduces the seismic isolation design in accordance with the“Standard for Seismic isolation design of building”.Foundation isolation is selected for this building,using LRB and LNR isolation bearings;Set seismic performance objectives for the entire building,distinguish key and common components from structural components,and set corresponding performance levels.Using structural analysis software YJK 5.2 to conduct response spectrum and time history analysis of the structure,Through comparison of analysis results,the seismic isolation scheme of this building is reasonable and can significantly reduce the seismic response of the structure.This project provides a good example for the wide application of seismic isolation technology in similar engineering.
