[摘要]长春奥林匹克公园游泳馆总建筑面积约34 000m2,平面为椭圆,长轴163m,短轴115m,屋顶为单向倾斜面,屋顶高度为20-05~34-7m。主体结构为钢筋混凝土框架结构,屋盖及斜柱采用钢结构。结构外观呈椭圆倒锥体几何造型,周边52根斜柱与地面夹角为50°左右,呈发散形,屋盖最大跨度70m,形成头重脚轻的态势。阐述了本工程结构体系、布置、节点、方案选型等方面内容,并着重阐述了本结构的创新点,即设计中让外围斜柱、部分内部直柱子与大跨度屋盖形成耦合受力的结构。结合实际工程提出了斜柱与大跨度屋盖耦合受力的设计方法,可为同类工程设计提供参考。

Abstract:Changchun Olympic Park Swimming Gym  has a total construction area of 34 000 square meters. The plane is elliptical, with a long axis of 163 meters and a short axis of 115 meters. The total roof is a one-way inclined surface with a roof height between 20-05 meters to  34-7 meters. The main structure is a reinforced concrete frame structure, and the roof and the inclined column adopt steel structure. The structure is in the shape of an elliptical inverted cone. The angle of the 52 surrounding inclined columns and the ground is about 50°, showing a divergent shape. The maximum span of the roof is 70m, forming a top-heavy posture. The structural system, layout, nodes, scheme selection and other aspects of the project were expounded, and the innovation of this structure was highlighted to make the peripheral inclined columns and part of the inner straight columns to form a coupling mechanical structure with the large-span roof in design. Combined with the actual project, the design method of coupling force between the inclined columns and the large-span roof was proposed, providing reference for similar engineering design.

Keywords:Changchun Olympic Park Swimming Gym; inclined column; large-span roof; coupling force
