［摘要］在框架-核心筒结构体系的基础上，提出了一种新型结构体系“框架-阻尼框筒结构体系”。对某200m高、采用框架-阻尼框筒结构体系的超高层建筑进行了多遇地震下的设计，通过周期和层间位移角对比，得出钢板阻尼墙在多遇地震下可以提供所需刚度。进一步对该结构进行罕遇地震下的弹塑性时程分析，通过对基底剪力下降程度、顶部位移对比、层间位移角、框架损伤、钢板阻尼墙耗能和有害层间变形进行分析，表明钢板阻尼墙在罕遇地震下能够充分耗能，降低结构响应，保护框架构件。最后，研究了钢板阻尼墙屈服位移对结构层间变形和钢板阻尼墙耗能占比的影响。初步论证了框架-阻尼框筒结构体系可应用于200m左右的超高层建筑中，合理设计下具有优异的抗震性能，为超高层建筑的结构体系选择提供了一种新的方案。

Abstract:Based on the frame\|core tube structure system, a new structure system, “frame-damping-framed-tube structural system” was proposed. A 200m high-rise building with frame-damping-framed-tube structural system was designed under frequently occurred earthquake. By comparing the period and the story drift, it was concluded that the steel plate damping wall can satisfy the required stiffness under frequently occurred earthquake. Furtherly the elastoplastic time history analysis of the structure was carried out under rarely occurred earthquake. Based on the analysis of the degree of base shear decline, vertex displacement comparison, story drift, frame damage, energy dissipation of steel plate damping wall and harmful story deformation, it was showed that the steel plate damping wall can adequately dissipate energy, reduce structural response and protect frame structure. Finally, the effect of yield displacement of steel plate damping wall on story drift and ratio of energy dissipation of steel plate damping wall was studied. It was preliminarily demonstrated that the frame-damping-framed-tube structural system could be applied to super high-rise buildings around 200m, which has excellent seismic performance under reasonable design, providing a new scheme for selecting the structural system of super high-rise buildings.

Keywords:frame-damping-framed-tube structure; steel plate damping wall; super high-rise building; elastoplastic time history analysis; seismic performance
