The application of external prestressing in reinforcement of concrete structures

Taken reinforcement work of one medium-sized commercial office building as example,external prestressed strengthening technique in reinforcement of concrete structures is introduced.According to the control of reinforcement construction quality discussion is made,at the same time corresponding counter strategies are proposed.Author points out that this technique greatly increase the bearing capacity of concrete structures and obviously improve the service performance of structures.
