Abstract:Xinjiang International Exhibition Center is the main venue of China-Eurasia Expo, and this project is the second phase project. The main structure is mainly divided into two parts: the exhibition hall and the roof. The exhibition hall adopts the frame structural system, and the roof adopts the string-truss structural system. The structures of the exhibition hall and the roof  were introduced as well as the stability analysis of the string-truss structure. At the same time, some detailed problems in the design were studied, such as the unsymmetrical sliding bearing, the butt of the cast steel and the high strength steel, the design of the progressive collapse resistance and so on, which can be used as a reference for the similar projects.

Keywords:exhibition center; string-truss; stability analysis; unsymmetrical slippage
