In recent decades, prestressed concrete girders have primarily been used in bridges worldwide. One of the common issues frequently observed in these prestressed concrete girdersis the end-region cracking due to the application of prestressing forces. Numerous repair and prevention techniques have been proposed and investigated in this field, including the application of mortar, fiber-reinforced polymers wrapping, epoxy injection, post-tensioning, and strand debonding. This study seeks to elucidate a methodical review on the current body of knowledge discussing the methods to repair and retrofit, and prevent the formation and propagation of end-region cracks in prestressed concrete girders.
