An anchorage for a tendon that includes a sleeve having a smooth tapered interior bore and a compressible wedge disposed in the sleeve. The compressible wedge has a smooth exterior tapered surface tapering from a wider end to a narrower end and one or more interior channels for receiving a tendon. The taper angle of the compressible wedge is greater than the taper angle of the bore. Thus, upon insertion of the compressible wedge into the sleeve, the wider end of the compressible wedge forms a wedge contact with the sleeve before the narrower end forms a wedge contact with the sleeve. Preferably, the bore and wedge are conical, and the wedge is formed of several symmetrical pie shaped resilient sections. Corners of the sections abutting at the interior channel are rounded. An inner sleeve is disposed in the interior channel, with the outer diameter of the inner sleeve matching the diameter of the interior channel. The tendon is held by the inner sleeve. A pre-stressed structure may be formed by anchorages at each end of a structure with a tendon in tension between them.

[ What is claimed is:] [1.] An anchorage for a tendon, the anchorage comprising:a sleeve having a smooth tapered interior bore;a compressible wedge disposed in the sleeve, the compressible wedge having a smooth exterior tapered surface tapering from a wider end to a narrower end and a first interior channel disposed within the compressible wedge for receiving a tendon, the interior channel being disposed such that tensile forces on the tendon during use are oriented along the interior channel;the smooth exterior tapered surface of the compressible wedge tapering to a greater extent than the smooth tapered interior bore at least in a first plane that intersects the first interior channel, such that upon insertion of the compressible wedge into the sleeve, the wider end of the compressible wedge forms a wedge contact with the sleeve before the narrower end forms a wedge contact with the sleeve;a tubular inner sleeve disposed in the first interior channel, the outer diameter of the inner sleeve matching the diameter of the first interior channel; anda tendon held within the inner sleeve without resin being located within the inner sleeve, the inner diameter of the inner sleeve matching the diameter of the tendon.
