Abstract
An anchor for a post tension reinforcement is disclosed. The anchor includes an anchor base having at least one wedge receiving bore therein. The wedge receiving bore is tapered in diameter at a single selected taper angle. An axial length of the wedge receiving bore is selected so that a minimum internal diameter of the wedge receiving bore is at least as large as an external diameter of a sheath on a reinforcing tendon. In another aspect, the wedge receiving bore is positioned in the anchor so that its longitudinal center is approximately collocated with a load bearing basal surface of the anchor.
