It consists of the main concrete structure at the bottom and the steel reticulated shell roof. The structure system, difficulties in the designing process, and the main analysis results of this project are introduced. Some key points are focused on during the designing process, including the situation of this beyond-code-limits structure, the seismic design, the design of free-form surface steel reticulated shell roof, the design of bonded prestressed beams, the calculation of thermal stress, and the elastic-plastic analysis, etc.Keywords: beyond-code-limits structure; long span reticulated shell; parameterized curved surface; over-length concrete structure; prestressed beam; thermal stress; elastic-plasticity作者简介:马洪步,硕士,工程师,一级注册结构工程师,Email:mahongbu@163.com。参考文献[1]董石麟. 新型空间结构分析、设计与施工[M].北京:人民交通出版社,2006.[2]JGJ 7—2010 空间网格结构技术规程[S].北京:中国建筑工业出版社,2010.[3]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.
