A number of issues during the process of structural design for this project were summarized and expatiated, as follows: the stress analysis of floor temperature for the super-long basement and related design measures, the analysis and design of seismic performance, the structural design of large-span steel corridor, the analysis of comfort level and the TMD damping design about the largespan steel corridor, the analysis and design of the big cantilever structure which was steel reinforced concrete and used to support the corridor. The measures for above mentioned difficulties were carried out during the design, and the results showed that the structure system not only met the requirements of the structural safety, but also reached the performance requirements of the building.Keywords: super-long basement; performance-based design; reinforced concrete; comfort level; TMD作者简介:黄嘉,硕士,高级工程师,一级注册结构工程师,Email:huangjia@vip.163.com参考文献[1]熊向阳,戚震华. 侧向荷载分布方式对静力弹塑性分析结果的影响[J].建筑科学, 2001(5):8-13.[2]杨溥. 基于位移的结构地震反应分析方法研究[D].重庆:重庆建筑大学,1999.[3]JGJ 3-2010 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,2011.
