Abstract
The present invention provides an early warning device and a ductility control method for a prestressed FRP reinforced structure. By setting a tensioning screw, prestressed reinforcement can be converted into non-prestressed reinforcement when tensioning screw failure occurs, and the structure is still in a safe state. This can improve the bearing capacity and ductility of the reinforced structure, while the ductility can be controlled and designed, thereby resolving the problem of easy disconnection and brittle failure between the FRP and anchors, and greatly improving FRP utilization and structural safety.
