Abstract
A wedge for a concrete post-tension reinforcement anchorage system is shaped such that the compressive force on the tendon after tensioning of the anchorage system is substantially evenly distributed over a length of the outer surface of the tendon that is engaged by the internal surface of the wedge. The external surface of the wedge may have a first section with a first taper angle and a second section with a second taper angle, the second taper angle being larger than the first taper angle. The internal surface of the wedge may have a first section with a first taper angle and a second section with a second taper angle, the second taper angle being greater than the first taper angle. An anchor with a bore with two taper angles and tooth profiles of threading patterns on the internal surface of the wedge are also disclosed.
