［摘要］高風(fēng)壓、高烈度地區(qū)的高層建筑隔震設(shè)計時存在隔震層抗風(fēng)需求與減震效果難以協(xié)調(diào)的問題，且罕遇地震作用下隔震層位移過大需進行限制，為此，提出在隔震層中增設(shè)變性能黏滯阻尼器形成組合隔震體系，利用變性能黏滯阻尼器的分段式性能分別控制風(fēng)、地震作用下結(jié)構(gòu)響應(yīng)。介紹了變性能黏滯阻尼器隔震體系的構(gòu)造、作用機理、設(shè)計流程，并以某29層框剪結(jié)構(gòu)為例進行了隔震設(shè)計分析。結(jié)果表明，變性能黏滯阻尼器隔震體系具有良好的耗能能力和隔震層限位效果，能夠同時兼顧高層隔震結(jié)構(gòu)抗風(fēng)與減震需求，在高風(fēng)壓、高烈度地區(qū)的高層隔震建筑中有較好的工程應(yīng)用價值。

Abstract:In the isolation design of high-rise building in area with high wind pressure and high seismic fortification intensity, there is a problem that the wind resistant and energy dissipation effect of isolation layer cannot coordinate, and the too large displacement of the isolation layer under the rare earthquake should be limited. It was proposed to set segmented-performance viscous damper in the isolation layer to form a composite isolation system, and the structural responses under the wind and earthquake actions were controlled by the segmented performance of the segmented-performance viscous damper. The structure, action mechanism and design flow of segmented-performance viscous damper were introduced, and isolation design and analysis were conducted on a 29-layer frame-shear wall structure as an example. The results show that the isolation system of segmented-performance viscous damper has good energy dissipation capacity and good displacement limit effect of the isolation layer. The system can take into account the wind resistant and energy dissipation needs of the high-rise isolation structure and it has good engineering application value in high-rise isolation building in area with high wind pressure and high seismic fortification intensity.
Keywords:high-rise isolated structure; wind resistant; segmented-performance viscous damper; energy dissipation
