佛山国际体育文化演艺馆结构设计

Structural Design of Foshan International Sports and Culture Center

佛山国际体育文化演艺馆为NBA级别的大型综合性甲级体育文化场馆。体育馆主体采用钢筋混凝土框架-剪力墙结构,大跨度屋盖采用带转换桁架的钢桁架结构。对地基基础、主体结构、预制混凝土看台、大跨度转换梁以及钢结构屋盖和转换桁架、结构超长等设计重点和难点进行了全面的论述。利用YJK、ETABS和SAP2000对整体结构以及钢结构屋盖进行了计算分析和包络设计,分析结果表明:整体结构和构件在各种工况下的指标均能满足规范要求,结构选型合理,受力体系明确,且有一定的安全冗余度。

Foshan International Sports and Culture Center has 6 floors above the ground and 3 floors below the ground.The total height is 32.60 m.The plane length is about 174 m,and the width is about 129.4 m.A total of 15000 seats are set,which is a large-scale comprehensive sports and culture venue of NBA level.The main structure of the gymnasium adopts the reinforced concrete frame-shear wall structure,and the large-span roof adopts steel truss structure with transfer truss.The key points and difficulties in the design of foundation,main structure,precast concrete stand,large-span transfer beam,steel structure roof,transfer truss and super-long structure are comprehensively discussed.Using YJK,ETABS and SAP2000,the calculation analysis and envelope design of the whole structure and the steel structure roof are carried out.The analysis results show that the indexes of the whole structure and components under various working conditions can meet the requirements of the code,the structure selection is reasonable,the force system is clear,and there is a certain safety redundancy.
