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
