［摘要］高烈度区的高层剪力墙结构隔震设计是隔震设计中的难点，支座拉应力控制、结构防倾覆是设计中的关键环节。对处于高烈度地区的某高层剪力墙结构进行了隔震设计研究,并对其进行弹塑性时程计算。通过对比普通刚度橡胶隔震支座方案、低刚度橡胶隔震支座方案、橡胶隔震支座+滑板支座方案和橡胶隔震支座+滑板支座+黏滞阻尼器方案这四种方案的施工难度、造价及方案合理性得出，低刚度橡胶支座隔震方案为优选方案。再对比隔震方案和非隔震方案，采用隔震方案的结构楼层剪力、层间位移角等主要指标相对非隔震方案均有显著改善，上部结构构件尺寸大幅度减小，既满足了建筑空间使用需求，又具有非常好的社会经济效益。

Abstract:High-rise shear wall structure design in high intensity seismic region is a challenge in isolation design. Control of tension stress in isolation support and overturn-preventing design are the two major problems. By elasto-plastic time history analysis, the isolation design of a high-rise shear wall structure in high intensity seismic region was studied. Comparing the construction difficulty, cost and solution rationality, namely the ordinary stiffness rubber isolation support, the low stiffness rubber isolation support, the rubber isolation support with sliding plate support and the rubber isolation support with sliding plate support and viscous damper, it is concluded that the low stiffness rubber isolation support is the best solution. Moreover, the seismic isolation solution and non-seismic isolation solution were compared. By applying the seismic isolation solution, the main indexes, such as storey shearing force and inter-story displacement angle, were improved significantly. The dimension of superstructure components was greatly reduced, which not only meets the requirements of building space use, but also has good social and economic benefits.

Keywords:high seismic fortification intensity area; isolation design;  high-rise shear wall; rubber isolation support; sliding plate support; viscous damper
