According to the structural system as well as the geological conditions, the manual hole digging piles were adopted by scheme comparision, which had larger bearing capacity and less cost. Beam string structure system was adopted in large span steel roof. Combination of design and construction helped release most lateral forces of the main concrete structure caused by large span steel roof. In order to reduce the roof drift and increase the lateral stiffness of the main structure, 8 shear walls were added, which fulfilled the architectural requirements as well. Some key vertical members were designed as elastic elements under fortification earthquake. Temperature stress was calculated for super long structure under the temperature load. The enlargement of the reinforcement ratio of floor slab helped reduce the temperature stress in the concrete as well as the shrinkage cracking.Keywords: gymnasium; beam string structure; treatment of super long structure; temperature stress; manual hole digging pile; performance-based seismic design作者简介：倪兴惠，学士，工程师，Email:nixh@acctn.com。参考文献［1］北京市建筑设计研究院.建筑结构专业技术措施［M］. 北京:中国建筑工业出版社,2007.［2］GB 50011—2010建筑抗震设计规范［S］.北京：中国建筑工业出版社，2010.［3］白正仙，刘锡良，李义生.新型空间结构形式——张弦梁结构［J］.空间结构，2001,7（2）：33-38.［4］符龙彪，陈才华，刘枫，等.中国国家博物馆钢桁架与混凝土结构的合理连接研究与设计［J］.建筑结构，2011,41（6）：26-30.［5］GB 50010—2010混凝土结构设计规范［S］.北京：中国建筑工业出版社，2011.
