The upper layers of 16th floor use a 5-layers-steel structure to connect together. The project is a out-of-codes high-rise building. The CQEB is frame-shear-wall structure system, the main structure is 92m in height. According to the characteristics of the project, the targets of corresponding properties were made for the important structural components. By comparing the results of the analysis of different model and software, in accordance with the structure of the seismic performance goal, the corresponding seimic strengthening measures were adopted for the building structure. The local complementary analysis is made for the important parts of structure, and the effect of the measures are proved with the analysis results.Keywords: high-rise building; connected structure; out-of-codes building; cantilever structure作者简介:张然,硕士研究生,Email:leozr@126.com。参考文献[1]GB 50011—2001建筑抗震设计规范 [S]. 北京:中国建筑工业出版社,2001.[2]JGJ 3—2002 高层建筑混凝土结构技术规程 [S]. 北京:中国建筑工业出版社,2002.[3]GB 50010—2002 混凝土结构设计规范[S]. 北京:中国建筑工业出版社,2002.[4]徐培福,傅学怡,王翠坤,等. 复杂高层建筑结构设计[M]. 北京:中国建筑工业出版社,2005.
