[摘要] 工程主体为纯框架结构，屋盖采用曲线大跨度钢网架结构形式，支座处利用了减震耗能技术。根据建筑设计要求，结构正面飞檐、屋面双曲弧面、屋面侧伸部分、背面围护及侧挑部分构成了结构设计的几个难点。通过工程中这些既联系又相对独立的多个子项设计，只要采取正确简洁的方法，就既可满足建筑功能的要求，又能收获结构的美感，是此类建筑结构的设计方向。

Abstract: The principal part of this project is frame structure. The roof adopt the steel grid structure oflong-span curve. The techniques of absorption of vibration and consumption energy are used in the pedestal. Base on the request of architectural design, there are some difficulties, such as the structure ofpositive cornice, hyperbolic cambered roof, part of the roof extension, the back-decoration and part ofthe back extension. For these sub-items of the project which are not only the mutual relationship but also the relative independence, if using correct and compact method to satisfy the requirements of construction function, moreover to get the structural aesthetic feeling. It is the direction for this type of structural design.
