Abstract
An anchorage for at least one pre-tensioned or stressed tensile element, wherein the tensile force is transmittable to an anchor body by one or several wedges, including a wedge-shaped layer which has a modulus of elasticity that is lower than at least one other parts of the anchorage, whereby the greatest thickness of the wedge-shaped layer, measured normal to the longitudinal axis of the tensile element, lies in the region of the anchorage which is near the load. The wedge and/or the anchor body may be formed at least by two wedge-shaped adjacent layers, with at least one of the layers being formed from a material having a lower modulus of elasticity than the material from which the further layer(s) of the wedge and/or of the anchor body is/are formed, and the greatest thickness of the layer is provided in the region near the load.
