摘　　要：海南省图书馆新建部分东楼、西楼主体结构体系为框架结构,以东楼的设计过程为例,阐述本项目的隔震设计研究与分析过程。通过对比不同结构方案的受力性能、建筑空间优越性、造价、施工构造等,确定采用地下室柱顶隔震方案。根据设定的隔震目标,合理配置隔震支座,并按照《建筑抗震设计规范》(GB 50011—2010)要求,选择合理的地震波对其进行分析。隔震分析结果表明,隔震支座满足不同工况下的受力与变形要求,整体隔震设计满足预设的隔震目标要求,罕遇地震作用下结构基本处于弹性状态。另外,针对本项目的结构设计关键问题进行探讨,主要包括地下室柱顶隔震受力特性、扭转控制效果及黏滞阻尼器在隔震结构中的作用分析。The main structure system of the new east building and west building of Hainan Library is the frame structure.Taking the design process of the east building as an example,the research and analysis process of the seismic isolation design of this project was expounded.By comparing the mechanical performance,building space superiority,cost and construction structure of different structural schemes,the isolation scheme of basement column top was determined.According to the set isolation target,the isolation bearing was reasonably configured,and the reasonable seismic wave was selected to analyze it according to the requirements of Code for seismic design of buildings(GB 50011—2010).The results of seismic isolation analysis show that the isolation bearing meets the requirements of stress and deformation under different working conditions,the overall isolation design meets the preset isolation target requirements,and the structure is basically in elastic state under rare earthquakes.In addition,the key problems of the structural design of this project were discussed,including the isolation force characteristics of the basement column top,the torsion control effect and the analysis of the role of viscous dampers in the isolation structure.
