［摘要］開封體育中心體育場建筑造型新穎，其結構下部看臺為鋼筋混凝土結構，屋蓋罩棚結構為空間管桁架結構。通過對鋼結構罩棚單榀及整體性能的綜合分析，給出了適合于該建筑體型的結構方案。對結構進行靜力、風荷載及地震作用等相關分析，確定了結構整體及大跨度屋蓋結構布置和關鍵節點選型等關鍵問題，并采用多種軟件對其進行了整體結構計算。對關鍵節點進行了方案比選，采用有限元軟件對典型節點進行了分析，驗證了節點的可靠性，計算結果均滿足結構安全性要求。 

［關鍵詞］開封體育中心體育場；鋼結構罩棚；空間管桁架；關鍵節點

Abstract: Kaifeng Sports Center  Stadium has a novel architectural style. The lower stand of the stadium structure is reinforced concrete structure, and the roof canopy structure is space tube truss structure. Through a comprehensive analysis of the single and overall performance of the steel structure canopy, a structural scheme suitable for the building’s shape was given. The static force, wind load and seismic effects of the structure were analyzed, and key issues such as the overall structure and the long-span roof structure layout and key nodes selection were determined, and a variety of softwares were used to calculate the overall structure. The key nodes were compared and selected, and the typical nodes were analyzed using finite element software to verify the reliability of the nodes. The calculation results can meet the requirements of structural safety. 

Keywords:Kaifeng Sports Center Stadium； steel structure canopy； space tube truss； key node
