［摘要］成都凯德风尚项目总建筑面积为609 301m2，位于7度区。对2栋2层的框架结构别墅和26栋19～20层的高层剪力墙住宅结构进行了隔震设计，隔震层设置在地下室顶板以上，采用了近4 000个隔震支座，是目前国内设计的最大的隔震小区，也是层数最多的高层剪力墙结构隔震项目。设计中验算了7度罕遇地震作用下结构的安全和8度罕遇地震下的结构抗倾覆问题，并设置了抗拔装置和抗风装置。计算分析表明，采用隔震措施可显著降低上部结构的地震作用，提供对建筑结构、房屋设施和人员的全面保护。

Abstract:The general floorage of Capital Land the Loft Chengdu is 609 301m2. The project is located in region of seismic fortification intensity Ⅶ. The two buildings with frame structures of 2 stories and twenty six building with shear wall structures of 19～20 stories are designed to be base-isolated, and about 4 000 isolators are adopted. The isolators are located between the basement and first floor. The project will be the largest base-isolated project, and also will be the highest isolated shear wall structure in China. The structures are designed to stand rear earthquake for seismic fortification intensity Ⅶ, and the overall overturning can be prevented under the rear earthquake for seismic fortification intensity Ⅷ. Devices to stand the overturning and wind load are adopted. It can be found that the earthquake reaction of the structure can be greatly reduced after using of base-isolation. The design of base-isolation can provide better protection to structure, facilities and people in the building.
Keywords:RC structure; high-rise building; base-isolated structure; time history analysis
