Abstract
In a stressing anchorage for prestressing elements (2) in part of a structure, at least one part of an anchor head (4) consists of a mortar-like mass in the area in which bores (3) are disposed to accept frustoconical wedges (8). The frustoconical wedges (8) are made of steel. Since the mortar-like mass on which the frustoconical wedges are supported is more ductile, i.e., more workable than the wedges (8), the distribution of load from the wedges (8) to the anchor head (4) takes place in such a fashion that marked peaks of the load are considerably reduced.
