Anchorage device for high-performance fiber composite cables

Abstract

A conical anchoring system to anchor one or more loaded, stressed or pre-stressed tension elements (9) comprising a conical anchoring casing and an anchor body (7) fitting into the casing and retaining the tension element(s). The boundary surface between the anchor body and the casing wall is substantially designed to allow free sliding. To prevent the tension elements from being torn out of the anchor body or rupturing the anchor body itself, the rigidity of the gradient material forming the anchor body increases from the site of entry of the tension element at the cone, that is from the front zone, to the rear part of the anchor cone. Substantially improved shear distribution along the surface of the tension element(s) is achieved thereby over the case of substantially uniform rigidity of the anchor body.
