Abstract:Through the example of Nanning Wanda Mao Indoor Theme Park Project, the design scheme of the project was expound, the design characteristics of foundation，the design of lower concrete structure and the design of roof steel structure were introduced. The steel structure of the roof was mainly introduced to the design parameters of the steel truss, structural stability analysis, moving load design, finite element calculation of key nodes, and concealed weld design. For the steel structure design of the roof, the conversion members that directly bear the amusement equipment were designed according to the Design rules for recreation facilities(GB 8408—2008), and the roof trusses were designed according to the Technical regulations for space grid structure (JGJ 7—2010). A brief analysis of the related issues of structural design was made for reference to similar architectural designs.

Keywords:Nanning Wanda Mao indoor theme park; type selection of long-span spatial structure; economic analysis; steel truss joint analysis
