摘　　要：文体中心的结构工程一般由于跨度大、结构形式复杂、用钢量大等特点而带来一系列施工难题。以某文体中心屋盖结构为研究对象,重点介绍并确定了曲型屋盖的节点标高,解决了折板四点不共面的问题;屋面由连廊相连,满足大跨度的空间要求,提出了中庭网架结构的支座设计形式;球形铰支座与桁架下弦采用抗震性能化设计,保证了受力传递的合理性;通过YJK、3D3S等有限元软件对文体中心结构的整体计算及主要构件进行分析,结果显示:该绿植屋面结构受力安全合理,分析结果满足国家和地方规范的相关要求,具有一定的应用和推广前景。The structural engineering of cultural and sports centers generally brings a series of construction problems due to the characteristics of large-span,complex structural form and large amount of steel.Takes the roof structure of a cultural and sports center as the research object,and focuses on introducing and determining the curved roof the node elevation solves the problem that the four points of the folded plates are not coplanar;the roofs are connected by corridors to meet the space requirements of large spans.The overall calculation and main components of the cultural and sports center structure are analyzed through finite element software such as YJK and 3D3S.The results show that the green roof structure is safe and reasonable in force,and the analysis results meet the national requirements.It has certain application and promotion prospects in accordance with the relevant requirements of local regulations.
