Development of steel structure building in China

The application of steel structure has a long history in our country. The development of steel structure building in China can be divided into three stages:

First, the beginning of the period (from 50s to early 60s), two is the low tide period (from the mid and late 60s to the year of 70s), and the three is the development period (from now on). In 50s, the Soviet Union's 156 reconstruction projects as an opportunity to achieve remarkable achievements in construction. In 60s, the state put forward the policy of saving steel in the construction industry, the implementation of the process and there are some errors, limiting the rational use and development of steel structure building. The introduction of light steel building 80s in coastal areas, the domestic construction steel structure workshop, the Olympic Stadium and a large number of steel structure, and high-rise steel structure building is built the first climax of development Chinese steel structure. However, China's annual construction steel is only 1% of the amount used for prefabricated steel structure, with more than 80% of the developed countries, the gap is huge. Fortunately, at present, the development of steel structure in our country has not been prosperous. Mainly in:
1.1 high-rise, super high-rise building from domestic and foreign cooperation to start domestic
China's famous high-rise, super high-rise buildings are mostly the product of Sino foreign cooperation, such as the Shanghai Jinmao Tower, the global financial center, Shenzhen Wang building, Beijing Jing Guang center. Sino foreign cooperative design plays an important role in promoting foreign advanced technology and training talents. Built in 1998, Dalian ocean Plaza (high 201m, 51) marks the domestic steel structure of high-rise building started, built in 1999 in Shenzhen SEG Plaza (291.6m, 72) is the world's highest building concrete filled steel tubular structure.
A large number of 1.2 of the rapid development of steel structure building with foreign companies in recent years, the influx of light steel building with its high degree of commercialization, fast construction speed, good use effect, wide application, low cost advantage gained rapid development. About 2 million square meters of light steel construction. In this context, foreign light steel structure manufacturers have set up branch offices in China, manufacturing plants, has been a large sales.
1.3 spatial structure has been further developed a large number of large span construction projects have been built. Such as the Tianjin Sports Center (diameter 108m, 1994), Shanghai 80 thousand stadium grandstand roof (in 1998), Shenyang Bo Exhibition Center indoor football stadium (144 * 204m, in 2000)
