［摘要］潞城全民健身中心是北京市行政副中心的全民健身体育配套工程。结构整体地下1层，地上分为游泳滑冰馆、网球馆、全民健身馆、篮球馆、旋转坡道五个相互独立的结构单元。建筑地下采用钢筋混凝土框架结构，地上为钢框架结构，各馆大跨度体育空间采用平面钢桁架。针对不同体育场馆功能及特点，分别对各场馆进行了力学性能分析。完成了篮球馆大跨度钢屋盖结构方案对比，对篮球馆长柱及屋盖进行屈曲分析以保证结构整体稳定性。对游泳滑冰馆重载大跨度楼盖进行抗连续倒塌分析及关键节点受力分析，考虑有节奏运动对楼盖使用功能的影响，以网球馆大跨度楼盖为例介绍了楼板舒适度分析，验证了结构具体良好的承载能力及刚度。旋转坡道建筑造型独特，设计采用斜撑+悬挂结构体系实现复杂造型，通过承载力分析、舒适度分析及钢支座有限元分析等论证了结构体系合理安全。

Abstract: Lucheng National Fitness Center is the national fitness sports supporting project for the City Sub-center of Beijing. The overall structure is 1 floor underground. The above-ground part is divided into five independent structural units: swimming and skating hall, tennis hall, national fitness hall, basketball hall and rotating ramp. Reinforced concrete frame structure is adopted underground and steel frame structure is adopted above ground. The large span sports space of each stadium adopts plane steel truss. According to the functions and characteristics of different stadiums, the mechanical properties of each stadium were analyzed. The comparative analysis of large span steel roof structure schemes of basketball hall and the buckling analysis of the long column and the roof were completed in order to ensure the overall stability of the structure. The large span, heavy-load floor of the swimming and skating hall was selected for anti-progressive collapse analysis and key joint mechanical analysis. Considering the influence of rhythmic movement on the use function of the floor, the comfort analysis of the large span floor of the tennis hall had been carried out and the calculation results showed that the structure has sufficient bearing capacity and stiffness. The architectural modeling of rotating ramp is innovative and unique, and the brace+suspension system is used to achieve the complex shape. Then the bearing capacity analysis, comfort analysis and finite element analysis of steel bearing were conducted to verify the safety of the structure.
