ABSTRACT:
A method for repairing damaged post-tensioned or pre-tensioned concrete structures by removing steel tendons and forming new concrete post-tensioned beams in their place. The method includes the steps of removing concrete above the tendon to be replaced while leaving concrete under the tendon, releasing any remaining tension in the tendon and removing same, preparing the concrete surface for a pour of new concrete, installing rebars perpendicular to the tendon, installing new tendon and anchorages, pouring concrete and post-tensioning the new tendon in the new beam formed.
