Evaluation for Flexural-load Capacity of Prestressed Concrete Girders with Broken Tendons

The use of low-grade material sheath grouting for PC girders has resulted in some PC girders initially constructed in the 1950s having insufficiently filled sheaths. The exposure of PC tendons in the sheath generates corrosion and rupture of the PC tendons, reducing the load-bearing capacity of PC girders. This research...
