［摘要］高烈度區(qū)的高層剪力墻結(jié)構(gòu)隔震設(shè)計(jì)是隔震設(shè)計(jì)中的難點(diǎn)，支座拉應(yīng)力控制、結(jié)構(gòu)防傾覆是設(shè)計(jì)中的關(guān)鍵環(huán)節(jié)。對(duì)處于高烈度地區(qū)的某高層剪力墻結(jié)構(gòu)進(jìn)行了隔震設(shè)計(jì)研究,并對(duì)其進(jìn)行彈塑性時(shí)程計(jì)算。通過(guò)對(duì)比普通剛度橡膠隔震支座方案、低剛度橡膠隔震支座方案、橡膠隔震支座+滑板支座方案和橡膠隔震支座+滑板支座+黏滯阻尼器方案這四種方案的施工難度、造價(jià)及方案合理性得出，低剛度橡膠支座隔震方案為優(yōu)選方案。再對(duì)比隔震方案和非隔震方案，采用隔震方案的結(jié)構(gòu)樓層剪力、層間位移角等主要指標(biāo)相對(duì)非隔震方案均有顯著改善，上部結(jié)構(gòu)構(gòu)件尺寸大幅度減小，既滿足了建筑空間使用需求，又具有非常好的社會(huì)經(jīng)濟(jì)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
