Design and research on awning structure system of National Sliding Centre for Beijing 2022 Olympic Winter Games
National Sliding Centre is the first snowmobile venue designed and built in China,one of the most difficult projects in design and construction for the Beijing 2022 Olympic Winter Games,and the first snowmobile venue to be set on the south slope of the mountain in the world.National Sledding Centre consists of three parts:the awning,the track,and the foundation.The awning is the shading system for the entire track and is a major design highlight.In order to solve the problem of solar radiation on the south slope of the mountain and realize the organic unity of the appearance,function and structure of the building,a new type of large cantilevered steel-wood combination awning structure is first adopted.The type selection,structure,force mechanism and design process of the new structural system were studied,and through the overall numerical analysis and local fine finite element analysis,the force response of the new structure under different design conditions was explored,and the feasibility of the new structural system was verified.
