摘　　要：通过对网架结构受力特点的分析及对球铰构造的重新设计，使预应力技术在网架中得到应用，从而提高了整个网架结构的受力可靠性，为高强度材料在网架结构中的应用提供了可行性，减轻了网架自重，节约了材料。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.
