［摘要］根据建筑平面特点与外型要求，结构内筒剪力墙Y向有效宽度较小，内筒高宽比为23。为避免设置结构加强层，并综合考虑各种结构方案的抗侧刚度效率及工程经济性问题，最终采用了带内柱的框架-剪力墙结构。通过内柱的设置及剪力墙的集中布置，有效增加了结构侧向刚度；同时由弹性分析可知结构局部刚度过大，为此进行了大震弹塑性分析，分析结果表明：结构受力合理，内柱与剪力墙筒体间框架梁进行设计加强，可满足相关规范要求。

Abstract:According to the plane characteristics and exterior requirements of the building, the effective width of the internal tube shear wall in Y direction was smaller, and the height width ratio of the internal tube was 23. The frame shear wall structure with internal columns was adopted to avoid setting up the structural reinforcement layer and to consider the efficiency of lateral stiffness and engineering economy of various structural schemes. Through the arrangement of the inner column and the concentrated arrangement of the shear wall, the lateral rigidity of the structure was effectively increased; at the same time, the local rigidity of the structure was too large according to the elastic analysis, so the elastic-plastic analysis was carried out under the rare earthquake. The analysis results show that the structural stress is reasonable, and the frame beam between the inner column and the tube shear wall was designed and strengthened, which met the requirements of relevant specifications.

Keywords:super high-rise building; frame-shear wall structure; elastic-plastic mechanism analysis; lateral rigidity
