Construction Technology of Large-span Space Pipe Truss

Large-span space pipe truss structure is of beautiful space configuration with reasonable load,high stiffness,light weight,single bar and good appearance.In recent years,this structure has been widely used in many provincial and municipal stadiums,exhibition centers and other public buildings,such as Shanghai Yangshan Port North and South Stone Bridge project,the stadium of Nantong,Nanjing railway station etc.which are all the typical large-span space pipe truss structures.Taking Yangshan Port North and South Stone Bridge as an example,the processing and installation technologies are studied and explored.
