| Abstract: | Baseed on the analysis of mechanical characteristic of the structure and special design of the sphere nodes, the prestress technique was applied in grid structure. Therefore, the dead load of the grid structure was reduced and a lot of steel material can be saved. Basides, the bearing reliability of the grid structure are increased. It is also pointed out that the prestress technique makes it possible for using high strength material in the grid structure. |
