Abstract: The equipment of French nuclear power plants is fixed on reinforced concrete structures with base plate with headed fasteners. EDF decided to carry out an experimental research program in partnership with LGCIE in order to optimize the service life design of the headed fasteners and identify margin. This article introduces the results of static tension tests on an anchorage composed of an anchor plate welded to four headed rods. The anchors are cast in place in a reinforced concrete block. The experimental campaign is carried out on real size anchors and anchors with reduced embedment depths. Tests on single headed rods are also carried out in order to analyse the group effects. The slide of the anchor plate, the strain of the head rods, the strain of the stirrups and the surface concrete block displacements are measured. The collapse of the anchorages is caused by a failure of the steel rods or a concrete breakout failure for a loading ranging between 60000 and 30000 daN. This experimental campaign will provide a data base enabling the development of numerical models in order to improve the design.
