The Scope Of Application Of Prestressed Steel

Wherever steel structures are applicable, they can be replaced with prestressed steel structures to improve structural performance and reduce steel consumption. Especially in the case of large span and heavy load, the economic benefits are more significant. The widespread application of prestressed steel structures is in building structures, such as stadiums, convention and exhibition centers, theaters, shopping malls, hangars, terminal buildings and other large public buildings.

There are also examples of using prestressed steel structures in high-rise buildings, such as the Development Bank Building in Johannesburg, South Africa, and the New Poly Building in Beijing. Another area with more applications is bridge structures. Many suspension bridges and cable-stayed bridges at home and abroad are engineering practices with mature technology. Towering structures are a type of using prestress to increase the rigidity of the structure. Due to the action of cables, the horizontal rigidity of the mast structure is greatly improved, such as the Sydney TV Tower, the Barcelona Telecom Tower, the Beijing North China Power Dispatching Tower, and many high-voltage transmission line towers. The application of prestressing technology to the reinforcement and reinforcement of service steel structures is rich in content and diverse. The research of prestressing technology for light steel structure and steel plate structure has been started, and its application and development in engineering need to be deepened.
