Shanghai Stadium with membrane structure has the hyperbolic saddle steel whose construction area is 280000000 square meters, which used the steel up to more than 5000 tons. The longest cantilever truss up to 73.5 meters is called “the world’s first suspension structure”. The project takes a series of high technology of construction control by synchronous building, air hanging point replacement, unit contract distribution, structure synchronous deformation and so on.
