摘　　要：国家网球馆钢筋混凝土看台结构是由48榀径向框架、4榀环向框架与外立面16组V形柱构成的新型抗侧力体系。根据看台观众视线与人数要求,环形建筑立面向外倾斜达32°,从而导致楼层构件将产生明显的环向拉力。外环V形柱与看台结构的联系较少,需要通过专门分析以保证其稳定性。考虑到本工程体育场固定屋盖为一个整体,而且看台结构向外倾斜角度很大,故下部混凝土看台结构不设防震缝与伸缩缝。立面V形柱采用型钢混凝土构件,是结构受力的关键部位,节点几何关系复杂,因此在工程中提出实用节点形式。The reinforced concrete grandstand structure of National Tennis Court is a new type of lateral force resisting structure. The structure is consisted of 48 specimens of radial frameworks, 4 specimens of normal frameworks, 16 groups of V-shaped columns decorated in the external facade. In order to satisfy the vision requirements and enough audience numbers, the building facade tilts outward up to 32 , so tension force exists in the floor component. There is a few link members between the outer V-shaped columns and the grandstand structure, stability analysis should be studied. Seismic joint and expansion joint were not arranged on the grandstand structure which can not be easily divided into several stable separated substructures. Steel reinforced V-shaped concrete columns are the key members in the whole structure, the geometry relationship of the joints is complex, so the suitable steel reinforced joints are proposed.
