ABSTRACT:
A method of forming a dead-end anchorage of a post-tension anchor system includes the steps of positioning a tendon within a cavity of an anchor body such that an unsheathed end of the tendon extends outwardly of the cavity such that a sheathed portion of the tendon is positioned within the cavity, mechanically inserting a fixing element into the cavity, mechanically inserting wedges into the cavity between the unsheathed end of the tendon and a wall of the cavity, and applying pressure onto an end of the tendon such that the fixing element engages the sheathed portion and such that the tendon and the wedges are in interference-fit relationship within the cavity. The fixing element includes a pair of fixing members positioned adjacent an end of the wedges.
