The building of the UAE Pavilion for the World Expo 2010 has an unusual outline, which expresses the shape of sand dunes. As a temporary building, the UAE Pavilion will be disassembled and reinstalled in other sites after the Expo. To meet these requirements, the roof structural system is designed as single layer grid shell with bolted connections which is typically semi-rigid rarely used in China. This paper mainly presents the shell connection design. Full-scale test of bolt connection and FEM analysis were carried out to determine the stiffness and load carrying capacity of the bolted connection. The effect on the overall stability resulting from the connections was studied. The result shows that the shell connection is typically semi-rigid and the FEM analysis results used for design are conservative. The analysis also shows that the change in stiffness of the bolted connection is more effect on structural stability rather than on structural mode and deflection.
