［摘要］開封體育中心體育場建筑造型新穎，其結(jié)構(gòu)下部看臺為鋼筋混凝土結(jié)構(gòu)，屋蓋罩棚結(jié)構(gòu)為空間管桁架結(jié)構(gòu)。通過對鋼結(jié)構(gòu)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(jié)構(gòu)方案。對結(jié)構(gòu)進(jìn)行靜力、風(fēng)荷載及地震作用等相關(guān)分析，確定了結(jié)構(gòu)整體及大跨度屋蓋結(jié)構(gòu)布置和關(guān)鍵節(jié)點(diǎn)選型等關(guān)鍵問題，并采用多種軟件對其進(jìn)行了整體結(jié)構(gòu)計算。對關(guān)鍵節(jié)點(diǎn)進(jìn)行了方案比選，采用有限元軟件對典型節(jié)點(diǎn)進(jìn)行了分析，驗證了節(jié)點(diǎn)的可靠性，計算結(jié)果均滿足結(jié)構(gòu)安全性要求。

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
