The project Expo Axis and its underground multi system is the landmark building of Ex-po Shanghai 2010. Its roofing system is composed of cable-membrane structure and sun valley steel structures. This paper provides a brief introduction on structural features of the membrane struc-ture and the steel structure respectively. For the membrane structure, topics on safety factor of membrane materials, determination of wind loading, stresses and displacements, failure analysis and earthquake effects are discussed. For the sun valley steel structure, the overall structural be-havior including internal forces and deformations and the design of nodal joints are introduced, and the effect of single member buckling on overall structural stability is also presented. It is proved that the long-span flexible tensile membrane roof and the single layer latticed shells of sun valleys all meet the design requirements.
