The Research Of Externally Prestressed In Reinforcement Concrete And The Application Of Engineering

The constructional structure of reinforcement and transformation is a traditional major since the construction appeared, but for a long time in history, people were accustomed to apply the experiences which they had gripped, lacks of the system analysis and the theory, and the technical level enhances is not quick, all of which cause that has not formed a discipline. The nearly ten years, because of building's maintenance and transformation are in great demand, the modern technology's development, it is gradually forming a new discipline and developing very fast. External pre-stressing technology changes the original structural stress distribution, and reduces the original structural stress level, which cause in the general reinforcement structure the stress and strain lag phenomenon to be able completely to eliminate, thus the added partial and the original structure can together work well, causes the structure total supporting capacity remarkably to be enhanced. But the present research of externally prestressed technology is not enough, in order to adapt the modern cities requirements of the reinforcement and transformation, therefore carries out "The research of externally prestressed inreinforcement concrete and the application of engineering" has a greater practical value for us.This paper summarized the modern reinforced concrete structure technology will, right vitro prestressed concrete reinforcement for the behavior analysis, Through theoretical analysis and engineering study and explore examples of the in vitro prestressed reinforced concrete technical principle and design methods. Among the in vitro studies for prestressed reinforced concrete structure in practical engineering is the application of a theoretical views justice and engineering reference value.
