The Olympic construction steel structures Brazil and key technology

The Olympic construction steel structure and key technology steel structures Brazil disgn , production, installation and testing monitoring technology innovation and technology, on the whole to achieve leading domestic and international advanced level, in some technology reached the international advanced level. Five aspects reached the international advanced level, 15 at the international advanced level, 10 at the domestic leading.
Large complicated steel structure disgn Optimization and the detail design of CAD technology, complicated structure, modeling is difficult, member type is various, the influence factors of component size and detail workload is big, the implementation of the optimization calculation with good effect on behalf of the project: the national stadium, national swimming center, the national stadium, etc.
Large-span prestressed steel structure design and construction technology, such as: BeiGongDa stadium & ndash; & ndash; The diameter of the world largest string a dome, the national stadium & ndash; & ndash; In the world the biggest span orthogonal two-way piece of string truss and Beijing university gymnasium & ndash; & ndash; A new string a truss structure system. The prestressed steel structure "technical specification standards and the high strength of prestressed steel bar standard of construction process to appear technical problems get solved.
Large complex bending and twisting box section member production and installation technology, including space bending and twisting entity 3 d modeling and flattening lofting software, space, bending and twisting plate a multipoint no die forming equipment and special software, space, bending and twisting plate a three rod coil molding process, welding thin wall box section processing, space, bending and twisting component assembly, 3 d laser measurement technology research and application and the Lord - time structure installation sequence and top time structure installation.
