［摘要］深圳國際會展中心是深圳市委市政府布局深圳空港新城“兩中心一館”的三大主體建筑之一，該工程為大型復雜展覽建筑。超大特殊展廳作為該項目體量最大的一個5萬m2展廳，屋蓋結構采用空間管桁架結構體系，下部采用鋼框架結構體系。詳細介紹了超大特殊展廳鋼結構屋蓋結構體系的構成，對整體結構進行了動力特性和變形受力性能分析，對在大跨空間結構設計中起控制作用的結構穩(wěn)定問題進行了分析和研究，對典型復雜鑄鋼節(jié)點和懸挑三角桁架連接節(jié)點進行了有限元分析。結果表明，超大特殊展廳鋼屋蓋結構選型合理，結構安全可靠并具有較好的經濟性，可為相關工程設計提供參考。

Abstract:Shenzhen International Convention and Exhibition Center is one of the three main buildings of ‘two center and one stadium′ of Shenzhen Airport New City planned by Shenzhen Municipal Party Committee and Municipal Government. The building is large and complex exhibition architecture. Super-large special exhibition hall is the largest in the project with the exhibition area of 50 000m2. Spatial tubular truss structural system is applied in the hall roof, and steel frame structural system is applied in the substructure. The structural system of steel roof of the super-large special exhibition hall was introduced in detail, and the dynamic characteristics and deformation performance of the whole structure were analyzed. The structural stability issue which played a controlling role in the design of large-span spatial structure was analyzed and studied. The finite element analysis was conducted on the typical complex cast steel joints and cantilevered triangular truss joints. The results show that the structural system selection of the steel roof for exhibition hall is reasonable, and its structure is safe and reliable, and it has better economy. This can provide reference for the relevant engineering design.
Keywords:Shenzhen International Convention and Exhibition Center; super-large special exhibition hall; spatial tubular truss; stability analysis; cast steel joint; finite element analysis
