Structure Of Prestressed Steel Products

The prestressing technology has been in existence since ancient times, and it is a technique used by the ancestors to improve the performance of living utensils and strengthen and strengthen working tools. For example, the cloth umbrella (introduction of prestress) can prevent rain and wind, and the barrel hoop (introduction of prestress) can be durable and leak-proof.

However, the introduction of prestress into modern steel structures has been a national condition for nearly 50 years. People consciously introduce stress into the steel structure load-bearing system to offset the load stress, adjust the peak internal force, enhance the rigidity and stability of the structure, improve other properties of the structure, and use prestress technology to create a new system can be called prestressed steel structure.
