摘　　要：对于9度设防地区的超高层建筑,其结构设计基本由地震作用控制,因此抗震设计尤为重要。建筑消能减震技术可在提高结构地震安全储备的同时,降低整体工程造价,是结构优化设计的有效措施。对位于9度区的超高层建筑进行了结构方案选型对比、结构方案优化、减震设计方案比选、剪力墙内嵌钢板优化。结果显示,钢骨混凝土框架⁃核心筒方案相对于钢框架⁃支撑方案具备更高的成本优势;框架⁃核心筒方案可通过精细化设计作进一步优化;在此基础上,对钢骨混凝土框架⁃核心筒方案采用两种消能减震方案进行比选,结果表明,采用黏滞阻尼器方案的结构抗震性能明显优于采用黏滞阻尼墙方案;最后通过增大剪力墙竖向分布钢筋配筋率,对低区核心筒墙肢中的内嵌钢板进行了优化。For the super high⁃rise buildings in the 9 degree seismic fortification area,their structural design is basically controlled by the seismic action,so the seismic design is particularly important.The technology of seismic energy dissipation for buildings,which can improve the seismic bearing capacity and reduce the cost in the mean time,is an effective method to optimize the design.The comparison of structural system selection,structural scheme optimization,the comparison and selection of seismic dissipation technology,and optimization of embedded steel plates in shear walls were carried out for the super high⁃rise building located in the 9 degree seismic fortification area.The results show that the steel reinforced concrete(SRC)frame⁃core tube scheme has a higher cost advantage than the steel frame⁃brace scheme;the frame⁃core tube scheme can be further optimized through refined design.Based on the SRC frame⁃core tube scheme,two energy dissipation schemes were applied and compared,the results reveal that the seismic performance of the viscous fluid damper(VFD)scheme is better than the viscous fluid wall(VFW)scheme obviously.Finally,the embedded steel plates in the core tube wall limb in the lower area were optimized by increasing the vertical distributional reinforcement.
