In order to meet the requirements of space and vision, the main steel structure adopts large-span single-layer lattice shell. The structural system and the selection of the member bar section were introduced. The structural deformation and internal force in every loading conditions were analyzed. Besides, the stability of the global structure and the practice of the typical joints were discussed as key problems. The results show that the stiffness and the seismic performance of the structure system are good and the stability of the global structure is great.Keywords: large-span single-layer lattice shell; deformation analysis; overall stability; typical joint作者简介：侯书利，学士，高级工程师，一级注册结构工程师，Email:410141483@qq.com。参考文献［1］GB 50009—2012 建筑结构荷载规范 ［S］. 北京：中国建筑工业出版社，2012.［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］CECS 280∶2010 钢管结构技术规程 ［S］. 北京：中国计划出版社，2010.［4］沈世钊，陈昕. 网壳结构稳定性［M］. 北京：科学出版社，1999.［5］王秀丽. 大跨度空间钢结构分析与概念设计［M］. 北京：机械工业出版社，2008.
