［摘要］為了研究高烈度區(qū)高層剪力墻結構住宅采用隔震設計的技術經(jīng)濟性，對某剪力墻結構采用隔震設計前后進行了較為全面的分析比較。多遇地震作用下，分別對隔震結構與非隔震結構的底部剪力和層間位移角進行驗算。罕遇地震作用下，對隔震結構與非隔震結構的耗能性能、層間位移角、剪力墻變形角以及連梁變形角等進行對比分析，考察結構的損傷情況。在此基礎上，探討了隔震結構與非隔震結構材料用量、工程造價與設防烈度的關系。分析結果表明，采用隔震設計后，結構的地震總剪力與傾覆力矩均可降低2/3左右，多遇地震作用下的最大層間位移角可減小40%以上，罕遇地震作用下的最大層間位移角可減小50%以上；設置黏滯阻尼器對于減小隔震層的最大位移作用顯著；剪力墻基本處于彈性狀態(tài)，連梁的損傷程度大大降低。8度（0-3g）設防時，隔震結構鋼筋和混凝土的用量均明顯少于非隔震結構，工程造價低于非隔震結構。

Abstract:In order to study the technical economy of high-rise shear wall structural dwelling houses adopting seismically isolation design in high-intensity seismic areas, comprehensive comparisons were made for a shear wall structure before and after using seismically isolation design. The bottom shear forces and inter-story drift angles of the seismically isolated and the non-isolated structures under frequent earthquakes were checked respectively. For seismically isolated and non-isolated structures, the energy dissipation performance, inter-story drift angles, deformation angles of shear walls and deformation angles of coupling beams under rare earthquakes were compared and analyzed to study structural damage conditions. On this basis, the relationship between the amount of materials used, engineering cost and fortification intensity in both seismically isolation and non-isolation structures was discussed. The analysis results show that the total seismic shear force and overturning moment of the structure can be reduced about two-thirds by the seismically isolation design; the maximum inter-story drift angle can be reduced more than 40% and 50% under frequent earthquake and rare earthquake respectively; the maximum displacement of the seismically isolation floor can be reduced significantly by setting viscous dampers; shear walls are basically in elastic state, and the damage degree of coupling beams is reduced greatly. For region with 8 degree fortification intensity (0-3g), the seismically isolated structure has significantly less amount of rebar and concrete used and lower engineering cost than those of the non-isolated structure.
